I have heard some people have had really good performance with Splitfire plugs in N/A 944's. I have used plain copper Denso's with very good results.

Any input is appreciated. :banghead:

Bosch Platinum +4s seem to work well...

When i had my 83 944 i used Bosche Platinum +4 which worked great. also great for high mileadge car since its a hot plug and will burn off some of the carbon build up.

I used them on my 951 and didnt work as good as they did on my n/a than I went to Denso Iridium plugs and used them ever since.
