Spark plugs

Had been running R6725-9/10 since 2005 (went single turbo) until about 2010-2011 when I switch to the newer R7420-9/10. Why, they just run so much better/smoother than B9/10EGVs.

People will spend big money for power mods then go cheap on plugs, why?

Been running the 2396 plugs for a long time now. Only recently tried the V-power plugs. Around 5 years ago I had a slight misfire at the top of 4th gear. using the 2396 plugs. Say it was 85% tuned. Ran 10.5 at 139. Guys in the pits got me to try the high dollar plugs. Did and the car ran 10.5 at 140 but with no misfire. Then I noticed the difference in gap between the 2396 plugs and the high dollar plug. Re-gaped the 2396 plugs and made another pass. 10.5 at 140.

the high dollar plugs do have there place but I'm not there yet. So far the 2396's have taken me to 145 mph in a 2600+lbs car with out spending lots of money on the ignition system.
