Re: Ngk-ur5
On NGK plugs the lower the # the hotter.. 6-7 heat range is a norm for a peformance motor.
Most people run the ac mr45t plug .

I have had less than desirable results using the NGK UR series in a turobcharged application. However this was in a car. Believe it or not I have found the best plugs for boost applications were the AC Delco. Sounds strange but true. I thought I would share this incase you ever decided to get into abnormal aspiration.

The ur and br plugs are a standard automotive plugand most are a projected tip.
In a blown ,nos or turbo application if your not careful it will get the tips I have melted a few on the juice

I use NGK BR series plugs in my turbo cars...they came with them. I run up to 21psi of boost in one with no problems, key is tune and no detonation.
My boat engine, built by Innovation Marine uses NGK's V-Powers #7's in my 500hp 502ci motor and in their 600HP 540ci motor. So....the NGK works quite well for making power.
