Ok after spending over an hour searching and reading on H-T, tryin to see if I should stick with my old NGK Iridium IX Plugs (ZFR6FIX-11) OR go with NGK Copper (BKR7E-11) for my turbo H22A which puts out like 300Whp, I am still kinda confused which ones to use...

What are you turbo H22/H22A guys using and at what gap setting ?? Thanks Guys!

go with the copper. gap is going to be different on every car. start at like .025 and tighten up if you need to.

Okay the car was tuned with a .30 gap on the iridiums...

Okay I am still confused by which sparks plugs to get lol - after spending the whole night searching, I found -

BKR7E / BRK7E-11 - most popular for turbo Hondas but can you guys confirm these work on the turbo H22A without ANY issues??

BKR7EIX - Iridium version of the above plug I guess and apparently stronger and better - do these really give BETTER performance compared to the regular ones??

Also, since I am making like 300Whp do I STILL need a 7 heat range plug or is my current 6 heat range Iridium IX plugs good enough??

Boostinb20!

I have seen the Tips on the Iridium PLugs break off and destroy motors stick with the copper plug

Turbo-charged

you are WAY over thinking this lol


go buy a set of bkr7e-11's, .030 .025 gap. at your boost and power levels it wont really matter, either gap will be fine.

we stock hundreds of these plugs at a time because we use them so much, including H22's

yeah I think I am gonna get them since I came across quite a few threads of the iridium breaking off and destroying the cylinder / piston Kinda wierd because you would think a more advanced plug would be better... confusing as always...

i prefer the coppers and they are way cheaper, which is ironic haha

ive never seen an iridium plug cause a problem however.


the only reason i see using an iridium plug is if your EMS needs a resistor plug, which NGK does not make anything with a heat range colder than 7.

however im sure we are all guilty of using a non-resistor plug, and very seldom to you run into any issues with that.

anything making big power we run a r5671a-8, 9, or 10 depending on the car.

Update : WOW, I was surprised today when I put in the copper spark plugs (BKR7E - gapped to .030) and the car ran bad!! I mean I could feel a complete difference in the way it pulled when I got into boost and it was not the same

So I took those out and put the old NGK Iridium IX (also gapped to .030) back and instantly I could feel a difference. Car accelerated so much better and the power was there - I know this is not the first time someone has experienced this but anyway that was my experience!!

I guess the Iridium IX is better - in my case that is...
