are most u guys using the rp7 plug, just wondering y on os web site they recommend the rp6 and rp8 but not the 7

also 2 weeks in a row i won with this motor, the local club race, and the skyrocket invitational at blue diamond!! this is the best motor i have used to date and trust me i have used alot, the power is insane i am 2 to 3/10th's of a lap quicker then my nova pts, and i am using nova 2015 med header with a 7mm insert, the powerband is so smooth it feels great and its very stable in far as tuning and easy to tune and very reliable... got to say never had so much pleasure out of a motor in 6 years!!

Not really, it recommends RP7 and comes with it.

Use the RP7. It's the best all around plug for the engine. If you have higher air temps or a long straight, go to the RP8.

Glad to hear you're enjoying the engine.

Hi "kyosho malaysia",

I can't seem to find a Nova 2007 pipe. There is the Nova EFRA 2006 pipe - part# N-51009.

Can you give me a part number or send a PM for a link.

Thanks.

-Markus
