The NGK extended reach 7's... just one step colder than stock should be fine.

phantom · Nov 10, 2004

what part #?

phantom · Nov 10, 2004

ZFR7F-11 ??

Swerny · Nov 10, 2004

those plugs are probably too cold for a Calgary winter Phantom.

jurgs01 · Nov 10, 2004

Denso IK22 iridium plugs.

then which one is good to use in under cold weather?

That i don't know for sure, but i would say the stock ones.
Unfortunately, they are $14 each at the stealership. :'(
Maybe the ZFR6F's ?????

jurgs01 · Nov 10, 2004

The weather doesn't matter. The colder plugs prevent detonation in FI cars. Either get the Zfr7F-11 or the Denso IK22 plugs. Same heat range. The denso plugs are iridium, so they will last longer than the copper plugs and will cost more. Your choice.

phantom · Nov 11, 2004

isn't that BRK7EIX is also Iridium? are they no good?

is BRK7EIX better or Zfr7F-11 (is this Iridium/copper)?

jurgs01 · Nov 11, 2004

BRK7EIX is iridium, but I don't believe it's extended reach. The ZFR7F are copper and extended reach. Our stock plugs are platinum and extended reach.

denso ik22s iridium, one step colder, and not extended reach. come pregapped at .032. don't worry about the not being extended reach. they run GREAT.

Not to contradict you, but I believe they are extended reach. They come up when you cross-reference them to the Zfr7F, so I imagine they are the exact same specs (except the copper/iridium difference). I am not 100% sure, but I will check on it.

jurgs01 · Nov 11, 2004

Alright, the Denso IK22 have a thread diameter of 14 mm, a reach of 19mm, and a hex of 16mm.

The PZFR6F plugs (our stock plugs) third letter (F) indicate the shell size. F indicates a shell size with 14mm thread diameter, 19mm reach, and hex of 16mm. This is the same shell as our stock plugs.

The first letter in our stock plugs stands for Platinum, but the second letter stands for extended gap (Z). Is this what is meant by extended reach??

Just in case anyone cares the fourth letter R is resistor type, the fifth 6 is the heat range, the seventh F is the firing end construction, and the two numbers after the dash is the pre-gap in millimeters (1.1mm)

For the denso IK22 the I stands for iridium power, the K stands for the thread and hex size, and the 22 is the heat range.

The letter J in Denso actually stands for extended electrodes (which I'm assuming what is meant by extended reach), so Spicynamja was right they are not extended reach. Every cross-reference I do for our car brings me to IK20 spark plugs so IK22 are the same 1 heat range colder.

I will be going with the IK22. If you want Denso extended reach copper go with the KJ22CR-L8, if you want extended reach NGK copper go with ZFR7F-11, if you want extended reach iridium NGK go with ZFR6FIX-11 (same heat range as stock not cooler). Hope this helps.

question is... with my setup:

iON 3" turbo back, iON FMIC, boosting from 8psi - 10psi, K&N panel filter.

plus CANADIAN WEATHER from -35 degrees in winter to 30 degrees in summer.

what should I get if I want to stick with NGK?

BRK7EIX or Zfr7F-11 or ZFR6FIX-11 ???

is it that hard to make this choice???? it's driving me nuts~~~

Stormtrooper77 · Nov 12, 2004

Phantom: Go to clubplug.net/canada. They are located out of Montreal I think. But it was the only place (in Canada) that sells the Denso IK22 and NGK's. I went for the BKR7EIX-11. They are iridium and one step close than stock. I did have to regap them to .032 though. That took about 2 minutes. But our local auto stores only carry NGK Iridiums up to the 6 heat range, nothing colder. And if you ask if the 7's can be ordered in, they will tell you that they don't exist. Same for the Denso's. Most I checked with hadn't even heard of them.

I've only had them in for a week, but so far the idle is smoother. Plus, our wheather will have very little bearing on the way a plug performs.

You make the choice. You have the information. If you can't look through information and decide then just stick with your stock plugs. The ZFR6FIX-11 are exactly the same as your stock plugs except iridium instead of copper. Anything anyone tells you is just going to be opinion. If you want my opinion of the three you chose I would go with the Zfr7F-11. The only downside would be that they are copper, so you would have to change them more often.

phantom · Nov 16, 2004

Stormtrooper77, thanks for the info. I think I would go with the BKR7EIX-11 then...

anyone knows how long do I need to change these iridium plugs (BKR7EIX-11), if I am running 8 to 10psi daily?

thanks.

stock msp plugs are fine for under 10psi!!! they are already (1) step colder...
