Review on NGK RC GMX081 Spark Plug 51117 by Paul Koehler

Over the years I have tried several harnesses in my 2002 Saturn SL2, in combination with OE NGK 5643 spark plugs and a new Delphi coil set my car is now running better with 200,000 miles miles . so it was when he was a young stag. I can't explain why, but these wires just feel better than the others and have a much higher quality silicone coating. I had cables at every local auto parts store and they are far better and about the same price. The only thing I will try next is pairing them with NGK (DIS) coils for the Saturns! Highly recommended and good value for "boot", no pun intended.
