I plan on running NGK RT6 plugs gapped at 32 for the sidemount magnacharger (boost: 4-5psi). Is this good for my application, I just want to get some more opinions on the subject. Thanks

 

We reccomend factory spark-m-plugs gapped to the factory spec......

The NGK would be my second choice.

 

many told me that stock platinum plugs give you false knock or something.... so I should really stick to my stock plugs,, could there be a gain if I got the Rt6's and had allen tune the for the blower or is that possible???

 

I was planning on using tr6s but a lot of people said that regular ole tr55s would be fine. Anyone else have any more input on this?

 

My truck runs better with TR6's than it did with factory TR5's.

 

Best plugs to run are TR6's gapped at 0.035... how they come out of the box. Factory plugs and TR55's are too hot for FI apps.

I'm a big fan of the NGK TR6 plugs. Running them on my 2005 supercharged Hemi Ram and my 2004 supercharged Saleen. Both are gapped at 0.035" and no problems, whatsoever. Saleen is running 12 lbs of boost and the truck is running 8-10 lbs.

 

should I gap mine at .035 with my blower making 5psi, or should it be .032?
Thanks for the help..

 

I would say you'll be safe with a 0.035" gap. I've run pretty much the same gap on my plugs with three different S/C pulley sizes ranging from 4.00" (6 lbs boost) to 3.25" (11-12 lbs boost). I'm currently running a 3.50" pulley and 8-10 lbs boost. I think initially I had them at 0.037".

Others can chime in who have more knowledge of your specific set-up/application, though...

 

I have no trouble makeing 450 rwhp with the same plugs that they installed at the factory....This is just my experiance though.....
