Hi All

I am upto changing the spark plugs on my hemi 5.7l 08 durango.. thinking of something with better fuel effeciency and some HPs. any recommendations most appriciated.

BTW anything which works with OEM coils & does not break any other system (coil over loaded etc..)..

Thanks

 

I have been using Champion iridiums for the the last 40,000 miles without any problems.

are you using with oem coils. does it makes any differnce to fuel & power...

 

I use a hotter plug because of the tuner, ported heads and camshaft that I am running. I do not think a platinum or iridium sparkplug will be noticeable compared to copper in a stock engine. It would not hurt to upgrade.

i was told that my 2008 ram1500 with 5.7 hemi has 16 sparkplugs. can anyone tell me.

 

The Hemi has 16 sparkplugs. One on the combustion side and one on the exhaust side for each cylinder.
