I agree, everyone I talked to said this was the best option! I am going with Motorcraft AWSF-22C plugs.Falcon said:performance spark plugs wont give you any real gains, just go with the cheaper ones.. just get autolight copper or the original motorcraft sparkplugs.
Anything made by Bosch sucks.Dark02Pony said:whatever you do dont use like bosch platnum 2 or 4 or any of those, go with autolight, i had bosch plat 4s in my mustang for about a week and it drove like garbage, switched to autolight platnums and it runs nice and smooth again
Actually bosch makes some really good OEM part for cars however the same quality does not go into their aftermarket stuff with most of it being made in china and by sub contractors so their overall quality is not as it once was. There are list of people who have complained about the quailty of there plugs and all you have to do is search the forum to find that out. Just dont expect many experienced Ford or Mustang people suggest using them. There is so many other companies making better products, but if you are satisified that is cool.Choppa said:you guys really dont liek bosch. i switched mine to the +4s and i noticed a differnece over stock i also changed my wires to. i dont think bosch are bad at all i mustve got a good set
Stock platnuim plug are good upto 100K. Now that means they can go longer or not even close to 100K. This all depends on how hard you drive your car and everything. Coppers are good for about 20K, and the same rules apply.Rick0636 said:Not sure how many miles are on my plugs, but it shows no signs of needing any, it had 27.4K when I got it, about 45K now, still going great! Stock Motorcraft Platinums are fine, Copper might be better, Autolite probably if you were going to supercharge or run Nitrous.
