As of right now, Im just using oem replacement sparkplugs. NGK R's.

The reason why I am asking this is because my car is cutting out. I can only go up to 7500 RPM's now because the cut out (or what ever is causing it) is so bad, It jerks me forward. As in accidently downshifting from being in 3rd, at higher RPM's (just using it as a figure of speech).

My set up includes P30 pistons in LS block, B16a Head milled, 450 cc injectors, GSR cams, KMS dual valve springs, Stock valve, OEM head gasket.

This recently started happening.

So what are you running for sparkplugs, in your "semi-built" to fully built motors? Your help is appricated.

Give this a try, the LSVTEC thread. BKR7E for 10-12 CR motors

damn. I should have read it a little more. I just skimmed threw it.

Thanks man

 

overall on my stock motor NGK $1.99 spark plugs with the spark plug wires are the best. they make the most power out of all spark plugs and its been proven by my friend since he tested it all out on dyno, but don't have graphs anymore.
