NGK 2396 6$ a plug, had great success with these up to 500hp. sparkplug.com has the specs. Need a thin wall socket.

Currently using 3857 for leading and 4311 for trailing. 30$ a plug.

rockauto.com has good prices and ship fast.

Hey. Just wanted to clarify. That was 570whp @ 25 pounds on e85. I'm running a similar setup and just want to see where abouts ill end up. I also switched to AEM V2. Thanks.

Nice. Could you post your dyno chart? I have a similar set up but had some issues that needed fixing before tuning can be completed.

the AR series requires the smaller plug socket and there is no interference w the plug rail.

i am told they are a touch cooler than the typical 10.

they do come in 8 and 9 heat range also.

given they resemble the stock OE plug (multiple grounds), they are of high build quality i would think they would be excellent in a 9 for stock to moderate hp apps.
