The cheap chinese filter that comes with the Trask Air Assault hit a wall at 120hp/5000rpm. Just got off the phone with K&N and we're 99.9% sure the K&N E-3226 is the exact fit replacement. On!y thing not 100% sure of is if the groove for the cover is actually 5 1/8" in diameter. Sure appears to be tho. He didn't have that spec available.
Dennis Kirk has them in stock and list them as fitting S&S E and G model carbs as well.
For anyone with a Trask air assault, this is the filter to run.
Trask was no help at all.
On another note, Bassani stood behind their pipes and an issue with the chrome finish. They don't have a set of the Pro Streets Turnouts in stock atm but are making some for me as we speak. No.questions asked and I can keep the old pipes. That's customer service at it's finest!.

Thanks for this info. I just ordered the K&N from Amazon and it will be at my house tomorrow! I have experienced increased engine temperatures due to the poor flowing air filter that comes with the A/C. we'll see how she does with this much better flowing filter in there. Ridin Dad YouTube channel switched to a totally different A/C setup for this same reason.
Now that is interesting. Seems to me that less air flow would mean less power. Less power would mean less heat.

Mine was red and oiless. We tried to wash it out just to be sure it wasn't oiled.
Trask suggested cutting the screen out but I knew that would be a waste of time.

oops.
I am here to report that the K&N filter I ordered based on the part number listed above (E-3226) did not fit my Assault A/C. The filter was too narrow and left a gap between it and the front chrome cover that screws into the stand-offs. @Zedbra - which model did you install? did the front cover get tight up against the filter seal similar to the Trask provided filter?
EDIT- well, after looking again, it seems I was sent the E-3225 filter instead and that must be the issue. my bad (or Amazon's, investigation continues)

my 107" TC is a blueprint build with high flow custom ported heads that have oversized valves. When I have to run my rain cover on the filter, I notice a big decrease in power and an increase in heat due to load on the motor. In fact, I can tell when this crappy trask filter is getting clogged up based on how hot my motor is getting. I was astonished it makes that big of a difference too. I have a PowerVision with Target tune WB O2's and the bike was Dyno tuned by one of the best master techs in my area. I've even tried playing with the quick tune function to add a little fuel to the tune but it doesn't help either.
