NGK (7746) IFR7G-11KS Laser Iridium Spark Plug, Pack of 1

Perfect for the K20A2Z engine in the 2002-2003 Acura RSX Type S. I let my spark plugs go too long because the change interval is 110,000 miles. Forgot whether they had been changed or not. The gap was quite wide and lot of material was gone. Runs smoother now with 214k on a 2002 that was purchased new 11-2001. Hoping to get 250k.

I bought these for my 2003 RSX to replace the stock plugs after nearly 90K miles. I was surprised to see that the ones I pulled out were still in pretty good condition. Don't skimp on your spark plugs. Iridium plugs are a bit more expensive, but when you factor in the fact that they last many times longer than copper or even platinum, they're well worth the price. I've noticed a very slight improvement in horsepower and fuel efficiency, but the real difference is in the feel of the engine. Whether idling or at high revs, I've noticed that my engine runs smoother and sounds "healthier". Remember, iridium plugs come pre-gapped. Don't try and adjust the gap yourselves or you may end up cracking off the iridium tip and rendering the plug useless. I'd highly suggest picking up a packet of dielectric boot grease and anti-seize compound from your local auto supply store. These are usually sold in small packets at the counter and can be purchased for peanuts, but they'll save you a lot of heartache the next time you need to change them out. A little goes a long way, one small packet of each should suffice for anything short of a V12 Vanquish. I highly recommend these plugs.

Works perfect on a Honda S2000Fires great works great and fits fineUsing on a 2001 Honda S2000Perfect Plugs

Perfect OEM fit for my 05 RSX Type S with K20Z1 engine. Old plugs were shot at 113k miles. Put a new set of these in, runs perfect.

These plugs were original equipment on my '02 Acura RSX Type-S. Scheduled maintenance says replace every 110k miles, I did 100k. The plugs I took out looked fine: no fouling, and the gap measured well. (I replaced them anyway.) These plugs are pre-gapped, but if you're the type who replaces his own plugs, you should also be the type to measure the gap before install.Very happy.

Timely shipped and good spark plug. Found incorrect plugs in my 2006 Acura RSX type S car from factory. Not from Japan....!!!Installed these correct spark plugs. Thanks.

Perfect, my Si runs a lot smoother and can instantly see the gas savings

Great product noticed the difference as soon as I installed them in my 2007 honda civic si well worth the buy
