Yeah I saw that for sure. I'm just shootin for 450 rwhp. That's a decent start with an intake and some cams

maybe 2hp for a K&N filter (if the stock one is dirty enough a gain will show). Maybe 5 HP for a K&N CAI. But intake and exhaust is always a good basis for other mods down the line.

Another question. I keep seeing this add for the K/N tat says 30 HP...any truth?

Heavily underrated.
A lot of the 350/350 dyno sheets you see from Cobra's were with less than 4,000 miles. It seems like 6-8,000 miles seems to be the final break in point for the Cobra. Most will dyno anywhere from 380-400RWHP.
I've seen a K&N setup add 15-20RWHP. Intake mods on a blown car make a much more significant difference than a N/A car.

RE: 03 cobra owners
If you look back at my dyno curve, the original 410 RWHP was Cat back only.
The JLT CAI got me from the 424 RWHP to 448 RWHP and from 458 RWTQ to 480 RWTQ

It was doing 400 RWHP with just catback? Isn't the flywheel only rated at 390? That's a huge jump for a catback.
