A Great Inexpensive Modification for the MK3 Focus
923731
This fit our 2012 Focus SE 5-spd perfectly.

It's strange.  On paper, the factory Motorcraft filter should flow more than adequately enough to supply the 2.0 L engine with plenty of power throughout its range.  Yet, after installing this AEM filter, there is a noticeable difference in throttle response, torque, and drivability throughout the powerband.  It really has made the car nicer to drive.  My only regret is not installing this sooner.

Somehow actual gas mileage, as tracked by Fuelly, has increased by about 2 mpg over 3 fill-ups since installing this filter.  I'm pretty sure it's black magic, this filter.

I bought this kit for use in my 01 Ford Focus. Kit worked great dash did require some trimming to accommodate my double DIN player. Looks very nice however be sure to use as many screws as possible as this kit will shift with just 2-3 screws per side.

A lot less expensive than going to the manufacturer, it worked with only a slight modification.

I bought this as I needed to remotely start and stop my Canon Cinema EOS C100 on a jib.  I was delighted to find that it worked like a charm for twenty bucks!  It even can power on and off as well as focus.  The focus doesn't moved quickly, but it does work on my L glass enough to pull focus on the jib.  If I could somehow switch the focus buttons over to the zoom rocker and even control the speed of it, it would be perfect.  You can only expect so much for twenty bucks, but it sure does give you a lot.  The clamp for mounting leaves a little to be desired, but again...it's only twenty bucks!  :D  Thanks for a working low price option for LANC!

So someone decided they needed to take out their frustration by smashing the taillight of my 2005 Pacifica. I really didn't want to shell out $200 for a OEM lens and found this one and figured it would be worth checking out.  It looks identical to the OEM and fits in the stock opening fine.  The only problem I has with my model year is that the notches for the taillight bulb (large 2nd hole) were not the correct size and the bulb assembly would not fit. After making sure everything else fine goos and I could properly secure it to the car, I decided to take out my Dremel and extend the notch that was too short to let me insert the bulb assembly. I got the bulb to fit and secure, but then noticed I had quite a bit of black plastic powder inside the lens that was very visible so I needed to get out the air hose and blow all of that out.

It wasn't as clean or easy of an install, but it's done, working great and I saved some $$$$

Easy drop in replacement for Splinter polarized lenses.  Even comes with a micro screwdriver to open up the frame and make the swap a piece of cake.

I installed these on a 1996 Mazda Miata. Direct fit with no modification. Connects perfectly to the factory harness. Almost too easy a modification for such an impressive improvement in light output! Low beams have a nice crisp cutoff. High beams don't cast light very high, but easily light up dark rural roads. Easy to aim. Not as even light output as modern HID projectors - these have a distinct pencil 'hotspot' but also spread the light far to the sides. In terms of performance, there is absolutely no downside compared to the factory sealed beam lamps. Aesthetically these are much more restrained than typical aftermarket headlamps. No goofy patterns or halos that look out of place on a 20+ year old car like the NA Miata. Only downside is, of course, the cost of these units, but after commuting with them in the dark both to work and on the way home, I am satisfied with the upgrade.

worked great as a fix for a P0141, Bank 1 sensor 2, on my 2001 Lexus IS300. the wire lengths were just right as well.

a few replacement tips:

* if you've having trouble getting the old sensor off, you can cut the wire close to the old sensor and use a 22mm wrench to get it off. worked like a charm. my Harbor Freight 02 sensor socket was a POS and spread, even with lots of liquid wrench, etc.

* the electrical connector for the old O2 sensor takes some finesse and patience to detach. you DON'T want to break this one off. Once I figured out which tab to press and which way, it wasn't too bad to get out.

* I couldn't find a way to elegantly get the plastic clip off of the body that's holding the wires away from the engine. I ended up breaking it off and then zip-tying through the holes that are left. FWIW, it looks like the garage that did the other O2 sensor a few years ago did the same thing, although it took me a while to realize that.

The 3rd party garage (not even the dealer) charged me $210 for the part, and then $110 for labor, to do a different O2 sensor on my car, which is even easier to access than this one. Wow. This is nice DIY low hanging fruit.

Like many small cars, my wife's Mazda had a modest single-tone horn ("meep!") that was completely ignored by clueless lane-changers. I was determined to find something more noticeable! I considered the various compact air horns (like the "Bad Boy"), but observe that they do not have a reputation for long-term reliability. (Thinking about this, I also decided that I would supplement, rather than replace the original horn, regardless of horn selection.) The sound of the 500 + 600 Hz "Sports Horn" (85112) matches the Miata perfectly. Like others, I do wish they were just a bit louder, but at least now the horns say "Hey!" instead of merely "Ahem..."

I added an auxiliary horn relay (with inline fuse for separate contact power) to operate these two added horns, which probably would not be necessary if they were replacements alone. For those electronically inclined, I also added a 0.35 second delay circuit to the auxiliary relay's coil, so that a rap of the horn still yields the original horn alone ("meep!"), but a mash of the horn button activates all three "meeHRAAAAAANK!!".

Even without my time-delay circuit, if you are concerned that replacing the original horn won't be sufficiently louder, consider adding a horn relay (with separately-fused power) and go for my three-horn solution. It did call for getting some more wire and crimp-on connectors to do the job right, but in the end I drilled no holes and "hacked" no existing wiring!

I use this with the Focus F-1 shoulder mount for my Canon 7D (mk 1) and I love it. There are 3 reasons why I like it over the mount that came with the F-1.
1. The camera attachment ring for the shoulder mount is separate from the attachment for a tripod. I can quickly switch to a tripod mount without taking the mount off.
2. The ring mount for the shoulder harness is slightly off center. I like this because it gives me more freedom of how I want the camera to sit against my hip/thigh when walking. That extra inch or two makes a big difference, it doesn't bounce as much mounted with this device.
3. The construction is much more sturdy, and locks onto the camera with no wobble.

I really needed this part to protect the motorized lens,  and finally bought it.  This only adds a little to the thickness,  but is much needed for protection.  This part is easy to install,  and is made of anodised aluminium.  A great addition to protect your investment.  When deciding on buying this part,  don't look at it as an expensive part,  look at it as an investment to keep your expensive camera working without malfunction.

This adapter is an INCREDIBLE piece of kit. It's built extremely well, and mounted my Super-Takumar 1:1.4/50mm lens to my T3i beautifully. This is a great thing to have for those on a budget, like myself, because it allows you to buy VERY high quality vintage lenses for $40-$100, and use them with your modern DSLR. I mainly use my T3i for video, and I do a little photography on the side. The image quality you get from these old M42 mount lenses is incredible. A modern equivalent for most of these M42 lenses are in the $400-800 range, yet you can pick up these old lenses second hand for a tenth of the price. Of course they won't stack-up to a $1,200 L series lens, but it will give you that shallow DOF "film-look" on the cheap because most of these M42 lenses have HUGE apertures.

I am VERY happy with this adapter. BUY IT!

My wife's 2008 Chevy Impala has had a non-working rear-driver-door actuator for a while now, and it seemed that the only solution was to replace the door lock/actuator with a new unit, which would set me back at least $130-150 in parts alone.

Assuming you're somewhat mechanically inclined and can follow along with most YouTube instructional videos, you really can't go wrong with buying these aftermarket door-lock actuators and giving the installation a shot. At under $10, why not give it a shot?

It took me 45-60 minutes from start to finish with completing this job, and would have taken less time if I was more familiar with the Impala door panel/lock removal process. In my case, the wires were not labeled so it was trial-and-error to find out which two wires controlled the OEM lock/unlock. Once I found that out, the rest was simple and re-installation was a piece of cake. As other reviews have mentioned, these new actuators are not as quiet as the factory ones, but hearing the solid "clunk" is a great sound, considering the alternative is a non-functioning door lock.

Great addition for the 3M 39045 Headlight Renewal Kit, use it in the refining process before polishing lens for a great, crystal-clear result.
(Tamper it with water exactly as with the original P3000 Trizact disc incluided in the kit)

I purchased this magnifier to improve my ability to manually focus my D70 camera with older AI lenses. I would recommend it for anyone who owns a D70, D70S or D50, as they all suffer from "tunnel-view" syndrome. I also purchased a split image focus screen from a company on eBay, and the combination of these two items has greatly improved the ease of manual focus. Not as good as a F2 (or even an FM) viewfinder, but a lot better than stock.

The kit included 2 new gaskets and plenty of extra screws.  The replacement process was straightforward.  The lens is clear.  I would definitely buy this again if/when the lens gets scratched.
