Which spark plug do you recommend

[zx12ninja]

I have been using the NGK BKR7E in my car for almost 6 months. Just recently I installed the ION FMIC and JoeP MBC @ 10psi. Over the past two weeks I have noticed the hesitation around 3500-4000 RPMs. Which plug would you recommend with these two mods.

Get the NGK ZFR7F-11. It's one step colder, copper, and extended reach.

They work great for me.

Thanks,

I went to my local auto parts stores today looking for the NGK's and Denso ones. Not one store had them in stock or really ever heard of them.

Any suggestions on where to get them from? Is one better then the other?

Got mine from www.sparkplugs.com. Had to pay for shipping but it beats going to every store there is.

No, they were not extended reach, they were pre-gapped however. All you have to do is tighten down until there snug, just don't want to over tighten. But that was a plus with the Denso's, you don't have to worry about the gap, since there already perfect fit.

Sorry to bring this up....again....but....

Don't our cars need the extended reach plugs?

Not that I know of. I have been using these Denso's for a month with no problems. They are better then the stock plugs. Also I will say this, when I compared the stock Spark Plugs with the Denso's, they were the same length, and looked identical in shape.

what is the correct gap for the NGK ZFR7F's?

I just went on that sparkplug website and could not bring up the Denso spark plugs. How do you find them and order them?

www.sparkplug.com carries denso plugs.

IK22 are what you want. Iridium, and one step Colder.
Im currently using the IQ20s.. got them for the cheap, and they work very well.

I was reading over the MSP manual, and I noticed the ZFR7F-11 or -8 are for the 1.6 litre engine. 2.0L must have the BKR. So I'm wondering why everyone is starting to use the ZFR7F-11 when our engines are 2.0L????????

Does it matter? I'm just worried if I used extended plugs when it shouldn't be, it'd hit the pistons or something. Can someone shed the light on this?
