They reach a little further into the chamber to promote a better, cleaner burn of the fuel.

plus they take up the remaining threads to prevent hot spots for pre-ignition.

Stock NGK's are BKR5E
Spool kit comes with NGK BKR7E
so I guess that's what I'm using now. . .

That's where I got mine from when I had nitrous back in 2002. I am fixing to go with the extended reach plugs from FP though.

Yeah we sell our colder plugs gapped to specs for $16.

FP will sells none gapped plugs.
Make them gap them for you. I didn't know that till I got them.

What about the iridiums?

 

[spoolinmp3]

The iridiums have shown no significant gains on turbo cars that are under the 300whp mark. Some Japanese publications have shown increase in HP on high end cars like the skyline ect

 

[1sty]

Terry, are you plugs $16 for all four gapped or $16 a piece?

 

[spoolinmp3]

Thats for all 4 gapped

 

[1sty]

How do i order them, I can't find them on your website?

 

[dominoy2k1]

i would like to get some too

 

[1sty]

I assume they are the colder ones for the turbo.
Is there actualy a horepower or drivability loss becuase of them.

 

[Norman@spool]

There is a slight insignificant hp loss but they are great for turbo apps. They are not on the site. You can call us and order by phone or send an online payment via paypal to spoolits@aol.com include 3.95 shipping and they will ship asap
