    QTY
    RR15SXC - Brisk Premium EVO Spark Plugs is rated 3.7 out of 5 by 3.
    Rated 5 out of 5 by from Improved Fuel Efficiency Confirmed Affter reviewing several SAE and other science articles on the benefits of surface gap plugs compared to ground strap plugs, I purchased a set. I ran 20+, identical highway routes over 1400 miles using new OEM AC Delco platinum plugs and the Brisk EVO. I used the same fuel, engine load, speed, driving conditions and monitor engine fuel delivery and performance. I swapped plugs twice in order to duplicate the performance differences. I observed lower fuel trim values using the Brisk, indicating the ECM was requesting less fuel under the same conditions. Using both the ECM fuel efficiency and fuel usage at the pump, I documented a full 2 mpg increase using these plugs. This is on a GM 2.4L DOHC, GDI engine with center fire plug location. Carbon build up was much less and in a centralized location indicating a full flame kernel development early in the combustion cycle. No need to index these plugs, the spark will occur at the most optimal direction based on cylinder turbulence and fuel concentration.

    Rated 1 out of 5 by from Does NOT fit 2016 Miata The search engine will tell you "it fits," but it does not. The 2016 Miata uses a 12mm thread not 14mm. Not a bad looking spark plug, but it costs the consumer and Jegs when there's bad information from a vendor.
