Do plugs, wires, and new coil really make a difference performance wise? I have 10K on my Touring Ed. PT, would it be adviseable to change out the plugs, wires, and coil?
Spark plugs and wires would probably be the minimum to get or return to better overall drivability. The stock wires, by some estimates, has over 3240 ohms of resistance, and often fail or wear out quickly. Aftermarket spark plug wires and using double platinum spark plugs should give you miles of trouble free performance and reliability. Changing the coil is up to you. Has I mentioned before in another thread, many of my buddies have been using a smaller spark plug gap, from .040 to .045 (stock is .050), and have experience better engine response/overall drivability and eliminated the slight hesitation on acceleration from a stop. There is another post about a TSB that changes the gap to .040 and specifying a newly designed replacement stock spark plug to solve the cold start fouling of the plugs.
