NGK# 4996 -- Laser Iridium Spark Plugs -- IFR5T11 --4 PCS NEW

Pulled out factory old one's and these were the same plugs they use on my 2012 scion xb, no problems as of today. Highly recommend

These spark plugs replaced identical plugs installed 100,000 miles ago. I was very satisfied with the performance of the NGK plugs over the past 8 years or so. I expect these plugs will perform just as well for the next 100,000 miles. If the vehicle is still chooching along, I'll grab another 4 pack of these!

Good

works good for toyota matrix 2004 and save some $ from the dealership

These are an economical replacement for the Toyota supplied plug, an $89 job at my local dealer. For about one half that money, you buy these plugs and do the simple job of changing them yourself. New plugs really perked up the car and improved the mileageI put them in my 2006 Matrix, and with the head being aluminum and the plug threads steel, I put a very small amount of anti-seize on the threads when I installed them. The next time I don't need to worry about getting the plugs out. Just avoid getting any anti-seize on the electrodes.

Fit perfectly in my MR2 Spyder. Now the gas needle barely moves, and feels a bit more responsive.

Amazon has these spark plugs fitting 2008 Pontiac vibe. They made a tapping sound upon accelleration, and after 6K miles the gaps were reduced to 0.035-38. The pistons might have been hitting against these spark plugs. I went to Advanced Autoparts and bought the OEM Denso SK16R11 and the tapping sound went away.

I used these in a 2003 Honda vtx 1800c, its one step hotter than stock and they work great! I would Recommend.
