Spark Plugs - Awesome deal

Hey guys, anyone know from experience if the copper tip spark plugs work best in the 5.7 Hemi, or would there be any benefit to getting the Platinum tip (copper core) ones.

I found a really awesome (if not sneaky) deal on Summit Racing's site.

http://www.summitracing.com/parts/CPN-3570/
^these are listed for $2.18 on their site, and there is currently a manufacturer's rebate for $2.00 off for each spark plug.

Just thought I'd share that deal!

And see if anyone had used those spark plugs in their Hemi.

For your year of HEMI the only spark plugs to use is copper cores.

Those are copper core, the tip material is just platinum.

Just buy regular champion copper plugs. There will not be any noticeable benefit from platinum tips.

The hemi stresses that you use standard copper plugs, no platinum iridium etc.
so your better off playing it safe.
