Anybody considered the gen II K&N FIPK for LS1's as a conversion alternative?

That's kinda what I was hoping for, I really don't want to go hackn on my radiator support if I can help it. I could prolly sell my GMPP CAI to my dad to recover some of the cash, she is a lil on the pricey side but if it;s better than the lid conversion I'd be happy!

So even if it did fit under the hood it really wouldn't be able to draw in fresh cool air without some sort of opening in the hood. Doesn't the ls1 cars have some sort of sheet metal piece that deflects the air up into those lids and those open filter type cai like pictured? I may be wrong but having the filter crammed under the hood there with no air souce seems silly to me! If it does work, sign me up! I'm in need of a good cai for mine.
I have been wondering this also, but it looks to me like the bottom of the filter would draw in cold air, while the top draws in hot engine air
It's in fron't of the engine so even though it's tight against the hood, it prolly won't pick up too much heat.
If it fits under a stock hood easier, and comes with a new radiator support that also fits, it might be worth it

One of these filters has to be perfect for mounting face down in front of the condenser.

Now if I could figure out how to make a tube like Colin91Z

I used a K&N RC5040 at first, but currently I'm working on a dual filter set-up for it. I can't finish it until the motor is back in my car though, Which should be early next week. The tube is a 3.5" 60* bend with a 1D radius.

Can you not just buy the ls1 lid package and use a radiator support from an ls1 car. I would think it would fit just fine. You may have to cut a notch in the hood but that would still be an easy task to do I would think. Maybe there's just something I'm missing.

^That I find hard to believe. I could see picking up 2-4 horse power at the crank shaft compared to an LT1 cai just for the lack of tubing causing turbulance but not enough to shave off tenths in the quarter mile. But hey, it might be! Has anyone on here swapped from a cai to a lid with results other than what they think it did. A lot of people do stuff to their cars and think it helps because of claims when it actually did nothing at all.

I still have my stock hood, I'll take some measurements to see if I can make it work. It seems to me that if guys can get the LS1 lid to work, minus the factory radiator cover this should work too. I'd rather trim/refiberglass the hood if necessary than hack the support. Then again, my GMPP CAI sure is purty! We'll see.

If you are stock cubes I would look elsewhere for more power. LT1 CAIs already flow way more then enough for a 350/355ci that is limited rpm wise by the LT1 computer.
I pulled the elbow off my TB during back to back dyno runs and gained less then 2rwhp with an open TB over the K&N CAI with filter. I think the actual number was 1.3hp, on a head/cam car through a 3200 stalled auto spinning to 6300rpms. Runs were literally within 2 minutes of each other-car never came off the rollers or cooled down.
Now, a 383/396 stroker spinning to 6800 rpm may very well see a benefit! Just don't go spending a few hundred bucks for literally one hp on your baby cam'd 355 rebuild.

Thinking of doing this, but hesitant because of EWP clearance to fan shroud. Does anybody know if you can clear a Mezier HD model when leaning back radiator for this?
