My preference, and biggest bang for the buck is...

BOSCH PLATINUMS, WR7DP good for about another 3 hp and noticable in the seat of the pants. $2.99 each

I haven't tried the following, but Bosch also makes double and 4 prong plugs... up to 5.99 each and ALL their RECOMMENDED Platinum Plugs are GUARANTEED to make a difference or your money back. In this case the WR7DPs.

The 2 and 4 prong EQUIVILANTS for the WR7DPs are #4310 for the Plus 2 and #4477 for the Plus 4.

IAP sells the BOSCH Platinums under the following IAP part numbers:

Single 31509 2.95
Dual 31512 3.99
Quad 44774 5.99
