i am looking for info on the best air intake . which ever kind it is home made or a kit you paid for . i would like to know what you guys think . thanks !

I personally think the fenderwell intake is best, but it requires, in all the versions Ive seen, that you cut out the fender support brace to get it to work. Which doing so is okay and will not harm the car, but Im of the opinion I dont want to be cutting anything on my car.

After that, I personally like the K&N (minus the K&N filter) FIPK system, but they seem a little over priced in my opinion. I would love to pick up a used one for a resonable price and if you could find one, it may be a good option.

After that, all the others seem to be pretty much the same design, Thrasher, Wizaired, etc. What you will need to consider is what to do with your PCM because it is contained within the OEM airbox. Some of the after market kits deal with this, others dont, so be thinking about that. There are some options out there.

Hope this helps out.

It whines a lot, but I like it.

i was thinking the k&n but i would rather use the AEM dry flow filter .

I've tried air boxes and the FWI....track times to prove that for my car the fenderwell intake works best. hands down.

Made my own FWI, and didn't have to cut any of the fender bracing out of my car. I just bent it out of the way.

My intake is a 9" K&N open cone, to a 4" 45* bent piece of diesel exhaust pipe powder coated red to a LS1 MAF, then to a LS1 TB. Throttle response is just freaking awesome on my car.

Farns, is that diesel exhaust metal? Im assuming so since you had it powder coated. Ive looked at Marine exhaust since its semi-flexible, you can get it in large diameters, and would be resistant to heat soak (though you could still wrap some reflectix around it).

Fenderwell - hands down. Whatever you decide to use - either a home-made version - or spend big bucks - you will see much better gains over the stock config and definitely over a "Cold" air intake. Those are for looks only in my opinion - the gains over stock are negligible at best.

Here are some pics of Farns' intake, then Brian's, then my old one (now Abrasive's). I bought the JMB intake - and yes it required a good amount of surgery to make it fit correctly and honestly I don't know that I'd do it again. I would probably go the route the Jason or Brian did, to be honest. But mine was purdy.

wow I can't believe someone lit this wick so soon.

Just know that a properly installed CAI gives you the cold air of a fwi and a shorter distance for the air to travel like an open cone.
Downside to a CAI - price and the room a box takes up
Downside to an open cone - heated air intake, moreso on a daily driver.
Downside to a fwi - long way for the air to travel and the filter is exposed to more dirt and some have said water.

I run an AEM driflow filter and wouldn't use anything else.

I don't want to beat the dead CAI horse anymore than it already has been. But from personal experience - with both Thrasher and MSP air boxes - my temps were 10-12* above ambient, pretty steadily - when I installed my FWI - my temps were 3-4* above ambient - at worst.
I think if you're going to have an intake - and it's intended to pull in the coolest air possible - then you should pull it from as low to the ground as possible. That being said - yes - you will have more maintenance (filter cleaning) than with a stock or CAI box, but it's worth it to get the gains. As for water entering the intake - not likely, unless one drives through excessively high water - like, over the wheels. In that case - they will likely have other issues than hydro lock to contend with.

With a FWI - yes there is a longer distance for the air to travel, but it's also coming in at a greater volume.

In the end - it's your car; your choice - do want you want.

Indeed - Where did you get your dry flow filter? I'm interested in running one, but don't know much about them.

I dont like the dry flo.....instead of sucking air through the main filter...it sucks it through a piece of foam. IMO...it doesnt offer great filtration. yes it will keep the water from being sucked up into the engine...but it eliminates most of the air being sucked in where the filter is....I dont see it filtering out most harmful particles.

this is just my opinion
