I always see threads popping up with people asking for the part numbers for the spark plugs they need. I am only going to list NGK's because they are what I have always used and have never heard one complaint about them.

Iridium - "NGK iridium plugs represent the ultimate evolution of spark plug technology and performance. The iridium center electrode is both stronger and harder than platinum. This allows NGK engineers to design an ultra-fine (0.6mm)center electrode reducing the voltage requirement for spark. This allows for a brighter, stronger spark from your existing ignition system. The ground electrode has a tapered cut at the firing end which reduces quenching for better flame core growth and increased ignitability. The combination of fine wire center electrode and tapered cut ground will increase performance, improve acceleration, and fuel efficiency."

8 - BKR8EIX - 2668
9 - BKR9EIX - 2669

V-Power Racing - "NGK's unique V-Power racing plug provides racing performance at an economical price. Designed to direct the spark to the edge of the electrode where it develops more rapidly, this increases ignitability allowing the engine to burn air/fuel ratios that would otherwise be too lean. Traditional ground electrode. In addition the NGK V-Power racing plugs are constructed with a copper core and triple interior seal."

8 - R5671A-8 - 4554
9 - R5671A-9 - 5238
10 - R5671A-10 - 5820

Traditional - "NGK traditional plugs are constructed for longer life and optimum performance. Corrugated ribs prevent flashover. NGK uses only the purest alumina silicate in its ceramic insulator which give all NGK plugs greater strength and better heat transfer. Copper cored and triple sealed to further aid in heat removal and prevent interior leakage."

So is it ok to run the iridiums on a boosted setup?

I've only run the traditional ones: BKR7E

The iridiums are supposed to last a little longer, but are much more expensive. All of these plugs are good to run on a boosted honda motor.

This is what I use

2668's

nice thread.

I use 2756's (BKR6E) on my SOHC, and now I'm going to run 1283's (BKR7E) on my GSR.

I use BKR7E #6097

I don't like Iridiums.

I've been using zfr7f (#5913) which is v-power and also a resistor plug. works good for me

This thread is also good for NGK part numbers.

I know some people swear by iridium plugs. I just never had any real good luck with them. I like the simple basic designs, they work tried and true.

i run the 4554's and have had any issues w/ them...probably not really pushin the limits but at 15psi outa my hx35...i can complain...not one hiccup

drintegra

useful info, many a times I have gottent the wrong plug from autopaarts stores

1992Si

You'll want to get those zfr's out of there. If you call NGK they will tell you those plugs will fall apart in our engines, they have proof. They will tell you to run BKR7E11's.

I am pretty sure the 6097's are the same as the 1283's, except the 1283's are pregapped to .044. They are both also the same price.

I also added a couple more part #'s

just curious, has anyone ever heard of using the oem plugs from a 91 crx si? i was reading a thread on here(a while ago) and could of sworn someone said something about them being great for low boost apps ........
