Spark plugs

[rgreen]

Just bolted up the ddm 28.5 cc race ported big block kit to my 5b 2.0, and my question is about what type of plug will give the best power. The kit came with a stock NGK plug but I read somewhere that an E 3 Iriniom (spelling might be off) plug is worth a little power. I have the ddm V1 pipe and stock carb. Any imput?? Thanks

Yea took it out for a little rip and it goes good. Not doggy at bottom end like befor with stock eng. Not tuned yet for peak top end, will run it in a bit first.

Stick with the NGK. You wont get anythng but a broken plug top with the taller plugs. IMO>

The cmr8hsa is best used in the touring car as it has a higher heat range and is longer.
for an off road car I use the cmr7h it's shorter and I've never had any issues, I've always carried a box of 10 plugs and still have 9 left.

thanks for the input. Just ran my baja today with my new Hostile mx rear tires and Wow! Those tires hook hard. Front wheels straight up from a dead stop. Loving it!!
