Spark plugs: Going along with my "Cleaner is better" approach towards the plug wires, the spark plugs are just as important and easier to replace then the wires. Right now I would recommend Bosch Platinum plugs. Available damn near everywhere (exept K-mart and other cheesy stores) these plugs will offer extended life over stock plug's and will offer better performance. Exact price varies on this product but expect to pay around $30.00 for 6 plugs. And expect a 3HP increase.UPDATE UPDATE UPDATE 2\13\98.....I was strolling through PEP BOYS today when I saw Bosch Platinum's on sale for $1.89 each. I couldn't resist. I bought 6 plugs and installed them in about a half hour. I am very happy with them..
