Performance motors require their spark plugs to be changed more often than most, particularly if the car has been tuned. With carbon build-up and electrode degradation, power loss and poor fuel economy will become more prominent, causing negative flow-on issues. Replacement as part of good preventative maintenance is recommended for any enthusiast. These premium spark plugs from original equipment supplier Bosch feature a tri-electrode design for greater performance and longevity, and are the same spark plugs that BMW fitted at the factory. Made in Germany.
