I'll be installing my Superchips Custom flasher tune and Billetflow 2.93 with idlers this week. I'm thinking this might be a good time to improve the plugs. What do you guys suggest? Thanks in advance for your help!:D

I've run Autolite 103's without problems. I'm currently running NGK TR6's gapped at .034. Lot's of guys are using Denso IT22's.
The Autolite 103's were $0.95 per plug and they were fine. :)

Just for reference I have a BF 2.76 pulley w/ all the idlers.
