I have four of these plugs in my 2002 Corolla with stock ignition and they are Fantastic! I just checked them after 11,636 miles and there is no electrode erosion on these plugs (Checked plugs with a wire gap tool)! I would suggest to everybody who changes their own spark plugs to at least check them around every 12,000 miles or once a year (even if they are long life plugs, reading the plug will let you know about any potential issues with the engine). If your looking to put better plugs in your Corolla, NGK Iridium IX is an excellent choice. Fuel economy on the Corolla does slightly increase ~1% but every little bit counts! Another pointer is to drive conservatively and (if you can) anticipate traffic flow, curves, hills and don't ride the brakes - increase your following distance and let the car coast down the road. God Bless and happy trails! NGK (5464) BKR5EIX-11 Iridium IX Spark Plug, Pack of 1
Have used cheaper plugs in my 2002 Ford Escort (Autolite, etc.), you can notice a difference in engine performance (although that's a highly subjective statement).
Only other plugs I currently recommend are the bosch.
My Honda Foreman 500 used to be very cold natured until I put this plug in. It now doesn't need to be started by choking much of the time and when I do have to choke the engine, it can be unchoked after starting where I used to run with choke for a while before it would stay running. Great plug.
These plugs fit perfect and installation was very easy on my 2005 Corolla. The car runs very smooth now, but the other plugs definitely looked worn out (they may have been original at 150k).
Recommended if it's time to change yours. For the price you cant go wrong. Shipping was great as always from Amazon!
Amazon stated this plug worked with my 05 legacy gt limited. It in fact does not. The plug here is meant for the non-turbo'd 2.0 motor not the 2.5 turbo. You can imagine the trouble this could cause.
Had to have the car towed to the dealer after the motor began to run poorly, heading to a stall in drive and shutter while in park. Dealer said no long term damage was done but that it could have been much worse.
Likely no fault of the NGK plug but Amazon's system for getting it wrong. Either way I am leaving this as a 1 star in hope that people searching will wonder why 1 star and save themselves the expensive troubles I faced. While Amazon covered the cost of getting my car fixed and inspected at the dealer, I see 2-3 weeks later their system still says it works. Dealer made it very clear these plugs were wrong and showed me the difference. It's visible. We spend about 10K/year on Amazon but I will likely not get auto parts again. Was my first time. - Fuel Economy - Spark Plug'
