[McGruffAWD]

Just got these from advanced..they are gapped .32 they look right. Are they?

With your mods, you should run NGK BPR7ES

ohhh and RE- gap those yourself. i heard that there is a possibility that they can be effected by transportation and the gap will change.

no, get BPR7ES plugs. Here is some info on NGK's: http://www.extrememotorsports.com/plugfaq.htm

Less chance of tips breaking off.

BPR6ES are stock
BPR7ES are for light to midly modded cars
BPR8ES are for heavily modded.

These are the tried and tested best plugs for DSM's.

I actually prefer the Denso equivalent. I think they hold up a little better. I think 1 range colder than stock in Denso is w20exr-u

when does it become better to switch to the 8s instead of the 7s.. I know its one range colder but how do you know when its time?

 

[rdrkt]

I couldn’t answer you for sure. I know that when I would go out tuning I would be seeing some knock and when I switched to the colder spark plug it all but went away. I needed a plug that cold because I was trying to make all of this HP on pump gas. Might not hurt to give it a try.

 

[larryd]

thats what im wondering.. if I should try a step colder and see if that helps me out on tuning.

rdrkt: Not that there is anything wrong with NGK's but how much did the Denso spark plugs cost?

What? All he has is a boost gauge. He should stick with the 6's until later when he turns up the boost. I'm no expert certainly, but I think some people flatter themselves and switch to the 7's too early (just my opinion).

You're right, I glanced at his profile and saw his "wish list", mistook it for his actual mods list; a very detailed wish list BTW.

6's would work better than 7's in his stock configuration. Switch to 7's after most of the stuff on the list is acquired.

thank you..it would be alot more detailed if i had the room. They cut me off before i can finish. I just researched and researched untill i found what i wanted. Anywho ya. I re-gapped them and put them in with my new Accel wires. The car runs great. Thanks guys.

There is no real price difference

 

[larryd]

could running the 8s make a performance loss?
