2 step colder spark plugs ??
I'm going to be ordering NGK 2 step colder copper plugs and wires and am wondering what the part # for this is? I know you just change the last 2 numbers ... but what is our part number for the stock ones?

Why?

BKR6E is stock. Or close enough, anyway.
BKR7E is a common turbo plug. There is no BKR8E. You're into race plugs at that point. |

I'm looking for race plugs basically.

Unless you're actually circle-track racing the car, there is such a thing as too cold a plug. And as an FYI, proper NGK "race" plugs are about $30 each.
A little searching did turn up one cross-reference that has the right dimensions- the IFR8H-11 (stock #5068). It's an irridium "street" plug, 14mm x 19mm, 5/8" hex, gasket seat, resistor, etc. They're listed at a mere $12 each. Let us know how they work out. I'm curious about this one myself. |
hows that one compare to the IK22 / IK20?

I don't remember which ones but I'm pretty sure I have the 7's, Iridium ones in my car. Has been running fine for 10k+ boosted miles

Looks to be a honda?
There's a only few basic combinations of thread diameter, thread length, hex size, seat type, etc. So any one particular plug is gonna fit dozens of different vehicles. It's like saying I run "Honda wheels". No, I run 15x7 wheels with a 4 bolt 100mm pattern and +41 offset. That they happen to also fit just about every vehicle Honda has ever made (as well as a bunch of Toyotas, Nissans, etc) isn't terribly important.

Actually, isn't the 5E also standard on auto 1.6s? Not sure I understand that one fully... I think as an experiment I may buy one of the IFR8s and stick it in my engine for a while- see how it compares to the BKR7Es after a few hundred miles. Some side-by-side photos may help illustrate this for folks. |

For some reason I also thought the 5 range was stock for our cars.
I had planned on running BKR7Es. |
