Colder Spark Plugs
 

I have a 91 crx si and i need to know which colder spark plugs should i get? I called around to pep boys and autozone and they dont carry colder ones just the OE's I would think that NGK's would be good. The OE part # is BCPR6e-11. I know the "6" is the temp right? So i need a 7?? And if so, where can i get them cuz at local autozone's and ---- dont carry em?? T3 turbo, stock D16a6 with decent fuel mang, intercooled and in desert climate....if that matters

Re:Colder Spark Plugs
 

go to advance aurto parts and order these NGK's part numer 3333. they are for a 1990 Saab 9000 turbo hard driving. u can look them up on the ngk web site. they are one colder than factory honda.

Re:Colder Spark Plugs
 

Get some NGK's that are 1 or 2 colder. I think im running NGK heat range 7 on mine.

Re:Colder Spark Plugs
 

I thought the number went lower for colder. ??? Autopart stores suck for things like that. They look at you stupid because they don't normaly deal with that sort of thing. If you're not looking for an OEM replacement or a 6ft. aluminum wing they don't know what to tell you.

whatever you buy, buy NGK dont trust any of those stupid denso firms or whatever that gives you +20HP just by changing into there spark plugs

Re:Colder Spark Plugs
 

Well, if your OEM part number is BCPR6e-11 you should look for a BCPR4e-11.

Are you sure? Don't the numbers go the other way to go colder? I've always heard you should go from 6 to 7.

Re:Colder Spark Plugs
 

yeah, i was also told to go from a 5 to a 6, or 6 to 7 higher the # colder they are??? right???? so if i have BCPR6e-11 i would want the BCPR7 or 8?? I'm really stuck on this cuz i cant find any ngk colder plugs? help me...

Re:Colder Spark Plugs
