white smoke....and its not the tires

Depends on what you want to spend...

I have a preference to Bosch Platinums... I've used the Bosch 2 plugs and like them. Bosch 4 plugs I've never used, but have installed and the folks I put them in for seemed to like them. But even the standard Bosch Platinums are better than standard plugs in my opinion. One of my friends used to foul out his plugs in his 67 Falcon every thousand miles or so with standard plugs... after he swapped to the Bosch Platinums, we were good to go for more than an oil change without having to clean them up.

If you can find them, I think that Splitfires are a heck of a lot cheaper than they were when they came out in the early 90's... We tried an experiment with them on a 302 with separate dual exhaust.

Both sides were running rich with the standard plugs... which were new. We ran a set of the Splitfires on one side and fired it back up... low and behold, that side didn't show a trace of smoke, while the other side was still running rich. That made me a believer.
