Exact replacement plugs recommended by Ford. Tricky to get to the back 3 cylinders but doable. After replacing old plugs 16 year old Taurus runs great.

These are the OEM plugs for my 2001 pathfinder and they were just replaced at 144k miles.  I wasn't have engine problems, just changed them because it was overdue.  We'll see if my car makes it to 288k...

For some odd reason these things and their boxes smelled heavily of incense...

Excellent plugs. I use them on my '04 Suzuki Marauder 1600. Imo they're better than the NGK plugs. Glad I found them!

Bought these for my 2011 Mercury 150 Optimax.  They were an exact match to the factory plugs that I took out.  I put them in, put the boat in the water and it fired right up. I'm your average blue collar guy who tries to do the things he can by himself instead of paying someone else to do it. I'm not a professional technician. These were half the price than buying them locally anywhere I could find them.  Couldn't be happier.

These spark plugs were a great deal and they were a perfect replacement for my 2014 Ford Focus. I opted to change them out early at 44K miles to maximize MPG and performance. They came pre-gapped from the factory with the utmost of precision. The threads felt strong and firm while installing. In the past, some cheap plugs' threads have felt soft that tend to give when installing. Not these. Easy peasy installation. While unscientific, I picked up about 4 MPG (~10%) since replacing them. Since I installed them, I have had no issues and have even noticed a slightly smoother idle.

Plugs work great.

That said, before installing make sure you check the gap between the electrode and pin at the tip of the plug (these should be at 0.044in).  Also note that these are not the original plug model that come with vehicle (DILZKR7A11GS).  Unhappy with actual packaging of these as all were floating loose inside the box when arrived.

The best plugs for imports! Car runs smoother, stronger, better mpg, and they last a long time.
This was the best price I found, 25% less than anywhere else!

I am happy with the plugs because they worked fine in my motor scooter. When I ordered the spark plug with the numbers in the scooter manual the Amazon company didn't have that exact number and suggested a different number plug and I didn't know if it would work, but it did. I have the feeling they know their job well.

Same plugs I always buy...one step colder for 4g69 engine...gap is around .032...some were a tad off, no biggie. Great price, and reasonable shipping time the Canada, thank you...

It is a Motorcraft factory part and is 100% plug and play. This unit has a new float and is ready to install. This is a part i would only replace with factory parts because of the time involved to replace it. It works great

When you do a major tune up it is always a good idea to replace these since you will most likely end up removing them if you are doing a timing belt and the valve cover gaskets. I had no issues with deciding which plug to run them from, just make sure you know your firing order!

This is a genuine Ford Motorcraft, KH634, molded/curved heater hose that connects from the thermostat housing outlet to the upper outlet on the Heater Control Valve, Motorcraft, YG350, used in a 1998 Ford Explorer V6 (X) Engine.  This heater hose fits perfectly and has a plastic heat shield attached.  Tightened this hose with a Breeze stainless steel clamp at each end with no problems.  After replacing all four heater hoses from the engine to the heater control valve to the heater core outlets, it was time to turn the engine over and check for leaks. Great news, NO LEAKS, the complete cooling system hose replacement, along with heater valve, water pump and radiator all continue to show no leaks. Picture shows the correct hose.  Thank You Amazon for providing quality named brand products and excellent service coupled with FREE shipping to my door, arriving safe and secure.

Awesome set of spark plug sockets.  I bought these to replace the spark plugs on my lawn mower and snow blower.  I've read reviews of different socket sets that they are hard to remove and I was afraid these would be the same, but they are not.  A simple twist of the socket and you can just pull them out of the plastic sleeve.  To place it back you simply insert it back and twist again.

After a lot of on line research, I settled on these for my 1997 Harley 1200 Sportster. They are reasonably priced and seem to be working at least as well as the stock HD plugs

Bought these for my 09 f-150 and They work flawlessly. Way cheaper than buying them locally and Motorcraft brand

Great plugs so far (about 500 miles).  Previously ran NGK TR6's in my GT500, running about 15PSI boost w/.035 gap.  So far these seem to idle/run even smoother (but don't new plugs always run smoother, will have to update review after $10-12K miles or so... noting that I replace my plugs about once a year anyways, so I always go with the inexpensive standard plugs and not the pricey iridium).
