what brand does everybody use and how do you like them. i am getting ready to change mine and am just curious. i plan on getting mine from the dealer so i will have motorcraft plugs and wires.
i went to Napa auto parts and got Belden wires and they were $150 a set and they were the best they had and i love them never faled me yet and i also have the motocraft plugs i put in
you wont notice a power gain by switching to aftermarket plugs and wires. you may think you do if you are replacing worn ones, but you will get the same feeling using stock OEM plugs and wires, they are MORE than adequate.
Bosch plugs have done nothing but give me grief in 4.0 SOHC engines, i pulled them out of the explorer and threw them in the woods. only motorcraft, or autolite, for me.
todays ignition systems do not require improvements on a naturally aspirated engine
^^ agreed. You can gain back some lost HP from old worn out components. Leaving plugs on 100,000+ miles and you will have gaps that have widened to the point you will lose some sparks and the gas will leave the cylinder and burn up in the cats. If you check your mileage regularly, this will tell you if you recovered some of the loss back. Better mpg = more HP with ignition components.
im not sayin that u will get a power gain but i notice i do get a little better fuel mileage but i also got some stuff thats not even out on the market
They are excellent for forced induction applications, but are not cost effective for N/A motors... The electrodes will bend when you break a piston... HAHA
