Question K&N cai, SLP cai, or other?

So I got the lt4 kit all finished up and now it's time for all the other things I told myself I would do after the install was complete. I'm sure they are fairly similar, but from the searching i've done it seems the slp doesn't fit well, but it does look better. Any thoughts from those who have both or any others. I also found during a few searches that the moroso is a pita to fit well. Pics of your setups would be nice also. Thanks! Also, I don't really feel like chopping up the hood for a lid.

Im running the SLP but did have to do some cutting to get it to fit right with the Trickflow elbow. Its really pretty minor....your call.

I got the K&N. The hardest part of the install was getting the filter on in that cramped space, other than that it went smoothly. I got mine at Kragen. If you call in the order they give you 10% off FYI

So does one actually allow more flow than the others?

I ran the Moroso and it was fine. Check out the LPE kit I believe its actually the cheapest one.

LPE? I will have to say that I don't know what the LPE is. I thought the K&N, SLP, and the Moroso were our only options unless you made your own. Where can I find the LPE?

i have have the SLP and the fit is fine, looks good, the one downside is when you do take the filters off for cleaning its in your best interest to take the plastic panels off from the underside of the car, and take the filters off from there, otherwise if you try to pull the whole works out the top you will end up damaging those filters

others will tell you another downside of the slp is that its metal, thus suseptible to heat soak, while it will get pretty warm on a hot day with the engine off, once you start it up it cools off pretty dang quick

Thanks, I got the link.

Does anyone have a picture of this on their car? Anyone actually have it? Maybe it's just me but it looks cheaply made, and of cheap plastic. Might just be the picture, but for the price it can't be beat I guess.

I haven't been to the track since I put in all the new stuff, but the best I could get out of her (I only made three passes last summer) with the 235/50/16's on it, and bone stock down to the paper filter was a 11.7 with a 2.2 60ft in the 1000ft. Hoping for much better times this year, but even with my slow times I still out ran an 03 gt 5spd with my 11.7. Best he could do was an 12.3...ha!
