Bosch #4227 works for me.....only $1.50 each...

 

are those the platnum 1

 

ef-1 autolites are the way to go man

 

Denso Iridium, I am a walking testament to these plugs and refuse to use anything else unless I'm using it for evaluation purposes.

 

the problem is my car was runnin good until it blew one of the spark plugs and now its detnating and i tryed changing a new coil pack just to see what diffrent it would made but its still the same

 

what heat range plugs are u using?

 

just factory spark plug wires and platnum 4 bosch

Only prob... most places don't carry the 7's (not even Autobacs and they have rows & rows of spark plugs on display).... usually nothing higher than the 6's (where bkr5 is the "norm"). But a customer of our who we built a 12.5:1 comp LS/VTEC has been using the bkr6 plugs for 6 months now, from the hot summer to the cold fall nights now w/out any problems.

 

i built a 12.3:1 compression motor for a customer and he kept bitching about a misfire.... Changed the plugs to 7e's and problem was gone. Also he is a dumbass and he was running lean as **** for awhile so that didnt help...

These high compression motors are untamed beasts, every one is different and respondes different

 

i dont know because it was running fine until it hit 1600 miles then it started to back fire around 5 thousdand rpm and soemtime it dont
