    Comments about NGK Laser Platinum Spark Plug (PLKR7A):

    Great product. Very easy to install in my Merc SLK350. Noticed a slight increase in power and gas mileage. Saw a very small 2% increase in gas mileage, but could just be driving style. None the less product works great so no complains.
