Default sparkplugs?
I have a 94 that is totally stock, it only has 25,000 miles but am going to change the plugs today. I have seen numerous threads on plugs but still not sure which ones people like the most, any suggestions?

There is pretty much a toss up, AC, NGK, Bosch and a few Autolite. For most stock engines everyone seems to migrate towards the platinum plugs. I was running Bosch Platinum +'s and they worked great...

Aren't those the 100,000 mile plugs that came in there? At the rate you're driving that thing the plugs won't be scheduled for a change until 2034.

RACE ON!!!

I am using the Delco Rapidifres. So far, I like 'em. My stock plugs weren't much after 77000 miles.

Default the bosch aren't bad.
Iridiums. hard to justify the dollars for the performance of a stock engine. the platinum +4's last. Idle well, get good fuel economy. good for the average driver or garage car. i wouldn't recommend them for a 500hp machine. but the 300hp stocker is great
