Questions our customers have asked

Would these spark plugs come pre gapped?
Yes they will come pre gapped within OEM specs.
What's the difference between the PLFR5A-11 and PLFR6A-11 are they gap differently ?
The gap is the same the difference is in the porcelain, and thus temp rating of the plug. We make these choices based on the power adders of a car. If you have questions regarding what is the right selection plug just give us a call.

Super clean idle. I have the kinetix high flow cats and dc intake on to go with it to bring out a nice hum in the exhaust.

Just basic mods done. Intake, exhaust & plenum spacer. Had recently replaced the original plugs to the standard NGKs but when ordering the Z1 5/16 plenum spacer went ahead and ordered the one step colder plugs. Dayuum my 2003 DE with 38k original miles just purrrrs now! Love it, Thx Z1!

with 88,000 Miles I'm pretty sure in my Z were factory original. they were very dirty and appeared to I have a rich mixture in the engine so I'm pretty sure the few bolt ons I've done without a tuner going to improve combustion rather than go lean. these look exactly like the originals and they fit perfectly. and the gaps look good.

I purchased a set of these NGK plugs for my DE 350Z that has a few modifications done like test pipes, headers, plenum spacer, intake and 3 inch exhaust. Along side a new tune, we were able to better the ignition timing and the car feels a lot better with this heat range. It does take a bit to start up on a cold start but after the car is up to temp it works just fine.
