just bought an 03 cobra and needed more power right away. i ordered 2.81 pulley, predator, afco heat exchanger, k&n cai, accufab TB and inlet, bassani converter x-pipe and catback. which plug should i use and how much power do you think i can expect? thanks

There's no strap on the Brisk so there is no need for gapping. Also, by design of the plug, Brisk has a larger and better fuel burn in the combustion chamber which results in added power that you see in these dyno's, a better idle, and smoother acceleration. LGS15 is what LFP is reccomending.

I used Denso's in the N/A 99 motor and again in the 03 setup, IT22s. They work great.

LFP has them. I would double check the gap before installing though.

Does someone have a specific listing of what plugs were stock in specific Cobras. In my reading, all I have found is that '03-'04 Cobras supposedly came with 3 different plugs (depending on build date):

AGSF-12-FM1
AGSF-22-FM1
AGSF-32-FM1

Is this true? If so, which cars got which plugs? :shrug:

This isn't a life-or-death matter...just a curiousity on my part. ;-)
