Which Spark plugs?

I m not worried about the price, I get a great discount....

I am thinking Denzo Iridium Plugs (as they added pick-up in the Explorer)

What is everyone's opinion on this?

Aren't you keeping the cobra pretty much stock? If so... no need for new plugs.

Ngk Tr6

I installed a set of the Denzo Iridium plugs last year and really didnt notice any significant change over the stock plugs with the exception of a lighter wallet ($$)

After the Whipple install, almost everyone I spoke to recommended the NGK TR6's and told me to change them each season and they cost far less too.

My only experience is the stock plugs vs. the Iridiums. I immediately noticed a difference in the idle - the iridiums are as smooth as can be. I'll probably stick with them on my next change.

We want to stay within the warranty for now, but add little bells and whistles here and there

If all goes as planned in the spring...mods will begin :headbang:

In that case.. I would just switch to the NGKs when the mods begin.

Thank Everyone so far, keep the opinions rolling :biggthump

Where can you pick up a set of TR6's I called Autozone and Advance and neither of them carry them?

We keep TR6's in stock and they are $2.49 a piece, which is about a dollar cheaper than you'll find at most places. We also have Denzo Iridium plugs in stock if that is what anyone prefers. If anyone needs a set let us know and we can get you taken care of.

I switched to the NGK TR6s and I recently noticed a few white specks on the #7 and #8 cylinder plugs. I also think the idle quality is a little worse with the NGKs on my car. I have a completely stock motor and stock Ford tune. I've decided to go back to the Motorcraft plugs [which are pretty good plugs to start with].

Cliff i wouldnt worry about plugs until you throw that ported B and pulley on then the NGK's will be fine!

I know. I just don't like white specks on the porcelain. I don't see how I could have detonation with the stock tune but the specks are troubling. For the time being, the stock plugs will go back in.

Lyle and I were just talking about what a Snow Performance methane injection kits would do to a ported/pullied Cobra. :slomo:

 

[Juggernaut]

were they preset gap or gapped by you or someone else!? b/c im pretty sure they come gapped from the factory perfect! :biggthump

 

[Flyn]

Gapped at .038.

I am wondering if the engine may have detonated a little when it was overheating on me a few weeks ago. That's entirely possible. Regardless, I like the idle quality with the stock plugs better [on my car]. I'll switch to Denso or NGK or whatever after the port and pulley.

not sure if that is a cause of your minor detonating could be ask Larry im pretty sure he should know

Susie--
I have a set of Denso IT22 if you want them 25.00. They only have about 200mi on them. I gapped them with a gap tool-NOT a coin gapper as you will screw up the electrode if you do.
I switched to TR6s when I upped the boost. Im going to go with the BR7s with the KB...........................3 more weeks..........................Lyle
