hi guys,

just wanted to get some of your opinion on which spark plugs are the best. I have to change my plugs myself and i was wondering if you could tell me how to gap them. i know i have to buy the gapper but i have never used it before.

thanks.

 

I run NGK BPR7ES and around .22-.25 gap. all depends on your setup and boost level.

 

How much boost are you running?

 

21-22psi

I would say even with stock cars and you change plugs i would go with .22-.23

i have went throw a good around of plugs and always found that range to be the best for high and low boost levels.

 

Gapping them is easy. Get yourself some feeler gauges and when they slide in without resistance, it's done.
If the opening is too wide out of the box, tap it down a little (lightly!!) and use the correct gauge to "open it up".

 

i am running 21 psi and have the same spark plugs in currently so i will get the same ones(NGK BPR7ES)

 

thank you all.

 

I prefer the BR7ES also gapped around 24 for normal cars and 23 for alchy guys

 

10-4 Al, very rarely a misfire at 32 PSI stock ignition. And you can get them on eBay for a $1 a copy.

 

ok good to see that you confirmed on that.

thanks.

 

is it this kind...?

snowmobile.....what is the different between BPR7ES and BR7ES...besides the "P"?

 

thats what i want to know too!!

 

I just got BPR7ES' yesterday and the freaking plug wires don't go all the way down! It's like the plugs are higher than the other ones. And when compared to the stock plugs the threaded part isn't as long so it's not going into the cylinder chamber as far?!

 

You cant use these plugs in an evo9 dude you have to buy the irdiums ones..
The P stands for protruding tip.

 

So all the people saying that they're running these plugs are wrong?

Lancershop sells the same exact ones for Evo's =/ http://www.lancershop.com/customer/p...?productid=169

I'm confused.
