    Rated 1 out of 5 by from Great Product Bought the RR12S racing plugs for my high horse power, highly modified LT4 engine. These particular plugs did not work for my application. My engine ran rough through the different RPM ranges and did not get better with tuning. Brisk plugs are a very good plug but just did not work for me, once I changed out the plugs to a different brand my car ran phenomenal. I cannot recommend this plug only because I modified my engine power and needed to experiment with different plugs to find the right fit. This plug may be perfect for you, just wasn't for my personal application.

    Rated 1 out of 5 by from Made the car run like BAD! I was looking for a colder plug for my setup. I ran NGK's and it was only one step colder. I tried these and noticed the car would not idle. Would load up and stall when I tried to drive on the street. Not happy with it at all!

    what is the heat range for a plug mean?

    Asked by: Merc
    Different engines call for different heat ranges for spark plugs. A racing engine or high compression engine will normally call for a colder heat range of plug to eliminate detonation.
