Crash712us Posted July 26, 2012 Report Share Posted July 26, 2012 I've heard of them before, from all I have read about them there not worth it. My personal opinion a spark plug will give you no performance gains what so ever, unless your plugs are bad already. But I am a firm believer in using OEM parts the plugs that came with your car are perfectly capable of lasting 100k+ however I don't recommend waiting that long to change. Motorcraft plugs are made by NGK and I would still be using but with meth kit install requires to install a colder plug. But since you are looking to do a meth kit I wouldn't waist money on plugs now and have to turn around and change them after the install cause the Denso's iridiums I am running will set you back $75 but here is the Denso part number so you can add to your list itv-22 Link to comment Share on other sites More sharing options...
casperl878 Posted July 26, 2012 Author Report Share Posted July 26, 2012 ok thanks chris, but your saying the ngk's arent good enough and cant be used if you have the meth kit installed? Link to comment Share on other sites More sharing options...
Crash712us Posted July 27, 2012 Report Share Posted July 27, 2012 Neither, NGK has excellent plugs. But NGK has no direct stock replacement plug listed for our cars, the do however make a colder heat range plug that will fit out car. That should be used in conjunction with the meth kit. But if your just looking for something to do and want change plugs I believe rockauto.com caries denso itv-20's which are a direct replacement plug for stock plugs.

steve142857 Posted August 10, 2012 Report Share Posted August 10, 2012 Hi, I bought Denso ITV-22 a few weeks ago and will have them installed at the same time as my aux trans cooler and T170 bought from Torrie... The mechanic guy at Ford dealer is asking me what needs to be the gap on those spark plugs... Anyone knows without any doubts? He asked me to ask Dan at Livernois to make sure, so if Rick, if you read this and can ask, I would appreciate, or if anyone else knows for sure. Thanks!

Crash712us Posted August 10, 2012 Report Share Posted August 10, 2012 I never gapped mine steve they come pre gapped. And the electrode is so fine galling could damage. And its my understanding plugs like these shouldn't be gapped. I'm just saying what I did, not making any claims to be factual. Link to comment Share on other sites More sharing options...
steve142857 Posted August 10, 2012 Report Share Posted August 10, 2012 The guy told me he wanted to double checked because they come pre-gapped but they are not always at what they claim to be... I have new plugs instead of 6, so if ever he screws one up, at least I have some spare... That said, I am pretty sure most of them are ok coming out of the box...

wildosvt Posted August 10, 2012 Report Share Posted August 10, 2012 An improperly gapped plug can being a pain to diagnose. Don't ask me how I know.. You will be down on power to boot. I never trust pre gapped plugs myself, While at the same time with the design of the plugs these days. I'm definatley cautious like Crash is saying with gapping them.
