Owner reviews for spark plug

I have a stack of 25+ index cards filled with notes about the care and service of the car. The factory service manual has notes and highlighted areas all over it.

Ngk Platinum all day

same everything but using a C2 Motorsport Stage 1+ tune. rippin!!

I run a cooler NGK plug in my boost increased and tuned ZR1 making 730 horsepower. They have been flawless and lead the market in the LS world also.

Today I ordered from VW TPS : - Quantum 5w 40 FS Oil & Filter - Oil Dipstick Tube - Fuel Filter - Pollen Filter - Brake Booster Pipe (Vacuum) (Pictured Below) - Interior Alarm Sensor Switch Have also ordered NGK Iridium plugs from Awesome GTI

I have the denso ikh24 and no problems for me.

ive ran the denso plugs in my stage 2 gli, and they worked great, had no issues with them.

Currently just swapped to Denso's IK20 like 2 months ago. They run pretty good. But now its mid summer over here and the car runs a little bit underpowered at those high temps.

I also just put in a set of NGK BKR7E's and gapped them a little large (.034) seeing as the ones I pulled out were at .043 That did nothing and the issue is still persistent.

I have solved so many drivability problems taking Bosch plugs out of misfiring engines.
