I need to know the right part number for the correct V-Power NGK plug to run in a B18C5 with 12.1:1 comp. This is N/A settup and I'm not sure what heat range I need.

 

I recommend Platinum PFR6G-11 or PFR7G-11
even the BKR7EVX-11 isnt bad either

 

BKR7E-N11 is available at Honda/Acura dealer under the part # 98079-5714J
PFR6G-11 is 98079-5614H. Both are good for high compression.

ITR platinums are available in one step colder as well.
NGK# PFR7G-11
Honda# 98079-5714H

 

I loved the BKR's, I change my plugs like I change my oil so the price was right.

 

check out http://www.clubplug.net they should have it cheap

 

Why not go to Advance Auto parts? you can get any V-Powers for 1.50$ a piece.
They have to order them but one day wont hurt anything, plus auto zone and all have them too.
I have been running the BKR7E-N11 and am pleased with them.
LATA

 

What about "DENSO 1K20" gap at 1.1mm ???

 

Does anyone use the Bosch ones? Or only NGK?

 

personally I think bosch plugs suck as I havehad bad experiences with them.

 

What are you guys gapping your plugs at for 12:1 compression? TIA.

 

1.1mm

 

Good lord! The PFR6G-11 is $12.00 each!

I think Ill go for the BKR7E-N11 for $1.75 each
Mike K recommends them...and he knows his shiet

i run the BKR6E-N11's and they are great...nice and cheap too, all of the local auto parts stores around here stock them so they are easy for me to find too

 

Yep, I just called B.A.P. and they have 21 of them in stock

 

They are stock plugs for ITR.
what can i say, you have to pay for performance.

 

Would they actually make a noticable differance over say the BKR7E-N11s?

 

they are only expensive because they are platinum......copper is actually a better conductor than platinum and will perform better....just wont last as long

edit: fixed my engrish

What effect does the length of the electrode (is that what is called?) have on the performance of the plug?





See how in the bottom picture the white parts is longer?

 

I see a noticable difference over copper.
I believe a lot of it has to do with the electrode design.


the bkr7evx11 are only 5-6 each.

You cant compare pictures like that.
The projection varies which is why they are labeled.

 

really? you think the PFR performs better because of its electrode design? because copper is known to be a better conductive element than platinum.

 

What do you mean? The picture shows exactly what Im referring to..I have seen both plugs in person.

 

Here is the BKR7E by the way...

 

EDIT: Nevermind

thats what they all say, but my car performs so much better with the fine
tip electrode.

 

interesting, does NGK have any fine tip plugs in copper rather than platinum? that fit the b18c?
