Perfect for 2004-2009 Prius
933037
I have a 2005 Prius, and this is a perfect fit.  Replacing the stock cabin air filter with the CF9846A  is one of the easiest improvements you make to a 2004-2009 Prius, not to mention the easiest maintenance item overall, and very worthwhile.  If you're considering paying $10 for an offbrand paper filter, just spring the extra $5 for the odor removal this filter has.  And whichever filter you go with, just do it.  Instructions are easy to find on YouTube, Priuschat, etc.  In 3 minutes online you'll become an expert, and then in 1 minute at the car, you'll be done.  The cabin air filter in the Prius collects a lot of dirt (mine had a serious number of  pebbles!).  It is also one of the first places a mouse will invade your Prius, giving you early warning to go find the "mouseproofing the Prius" threads on user groups before the critters can invade more seriously and/or chew up a $1000 wiring harness, to hear some people tell it.

Perfect replacement for a 2012 Prius C Three (driver side). Easy to install.

Just in case you need the other two rubber inserts for Prius C:
85214-68030 fits the passenger side wiper
85214-52060 fits the rear wiper

Works fine. Hardest part was getting the old one apart. Wish it came with a screwdriver and a set of directions. I have a 2004 Prius so the chip looked different.

This fit perfectly in my 2008 Prius. It was extremely easy to put in. i will forever replace my own air cabin filter. I can't believe I have been $20 all this time to get this done at a car shop.

I have replaced spark plugs for my 04 Prius with this one.  Exactly the same as the original plugs.  My Prius got 3-4 mpg better after replacement.  Will recommend to others.

So happy I found this - I was going to pay a ridiculous amount of money at a dealer. Fits my 2004 Prius perfectly, and took about 2 minutes to install. If you don't know how to, just search on YouTube. Simple as could be! Thank you :)

I installed this myself in my 2005 Prius and it works perfectly, looks great.  Actually, the main issue is it looks better than the other 10-year-old tail light assembly.

I only needed/used the orange plastic prybars, but they've been very helpful and the price was right. I needed to remove and replace the stock radio in my 2015 Prius. The pry bars are soft enough to not scratch the delicate parts, but firm enough to get the job done. They do wear after a while, but that's the point - the parts give so your car isn't damaged. I can't comment on any of the metal tools.
