i have been doing some reading and talking to some people regarding plug that are suited for turbocharged applications. i currently run the NGK platinum BPR5EP-11s in my straight gas 250 with a 0.85 gap set for gas as recommended by a gas tuner. overall i am very pleased with their performance. in regards to boosting a car i have been told that you should run a colder plug, in the case of ngk a 6 or 7 for higher boost leves which makes scense but i was also told that you should run a resistorless plug? why? also i it recommended to run a smaller gap such as 0.85 for turbocharged engines?

I had the standard plugs in for my first tune after the car was turbo'd and there were no problems up till about 12-13psi, then the car started to misfire. The tuner fitted LPG plugs with a 0.8 gap and no more misfire, and the car has seen 20psi.

I've got denso plugs with a 0.6mm gap atm.
But i'm on LPG too.

Two things required .. Close gap on plug as boost rises.. And fit colder plug for every 100 h.p.. Unless low comp pistons are fitted...
An MSD / Crane system helps....
