I am upgrading my 05 Saleen with the Saleen Extreme Parts Kit, which will up the power to 475. With this upgrade, will I need to upgrade my sparkplugs to colder heat range sparkplugs due to the added power?
The new colder range plugs are expensive as hell. The advertised price is $17.99 each.......OUCH! I found a guy that's going to send me a set for $75.00.....what a bargain! In the meantime you can gap your originals down to about 25-30 thousandths for good performance. If you want I can hook you up with the guy. He claims to have a few sets left.
