Which cold air intake would give the best gains for my 2007 Acura TL between Injen, K&N, AEM, etc...thanks

chek and see wich one has less bends and a better fillter mix and match to make the best most times but if u look closely they are probably the same shape pipe and quality of filter so go with what u want k&n or aem or any other brand. the amount of $ u want to spend is the real ?

It is really pointless to install a cold air intake with out modifying any other parts. There wont be much HP gains.also with a cold air intake, you also risk Hydro locking your engine, but there are ways to prevent it.

You have to look at the actual construction of the product instead of just brand names.. your objective is to provide as smooth and COLD a path as possible for air to come into your throttle body. Apart from looking out for gentle bends, you gotta also take care that 1. the pipe should match the diameter of your throttle body intake as possible to avoid turbulence. 2. pipe should be insulated so the cold air from outside remains cold and is not heated by the engine bay. (you can wrap with abestos fabric, ceramic coat it or get a carbon fibre pipe made) The filter gotta be of reasonably good quality.. I've tried Apexi with excellent results vs. other big brands. HKS and AEM's filter elements are pretty good too..

Not K&N.They make performance filters. They will give you 1-3HP.Injen and AEM will give you at least 10HP. Go with one of those. I think AEM is cheaper.

Do not waste your money on that crap. Get the computer reprogram, worth every penny on it and will give you better power than that junk. If you do not like it, you can go back to factory settings without getting dirty.

All three brands you mentioned should be good products. AEM, perhaps is the biggest player in the market, and has a proven track record. If you visit Acura enthusiast websites, you'll see a range of performance gains (from posted dynos). Searching the Internet will provide a range of HP gains, ranging from ~ 7 whp to 17 whp gains. Personally, I think the AEM product probably delivers around 12-14 whp gain...from a composite of various dyno posts & websites.CAI is the very first performance mod worth doing since you'll get the most powre gains for the $$. You don't have to upgrade your exhaust, but doing so will enhance the overall results. Also, there are no 'cheap' chipsets for your model of car, though companies like AEM also make a $1,500 (offboard) ECM module. Be very wary of outlandish claims from manufacturers of these accessories. There's not a lot of hidden potential to be had, and you're going to face compromises, such as reduced fuel economy. BTW, on the other hand, a CAI system can actually improve your fuel economy. I use AEM on my '00 V6 Accord &'06 TL. On an open highway at legal cruise speeds, I can get 32 mpg from both cars (also have catback exhaust, & Denso Iridium plugs) installed.

I get 30~32 MPG with 87 Octane fuel on my 3.4L V6 03 Impala at 70 MPH on the Hwy. With factory all, cruise control on and AC. It comes with a factory cold intake, is not a shiny metal tube but a plastic one with an air box that has an intake behind the driver side headlight. And the best of it is "free", it came with the car.

injen is good k&n may give you 15 to 20 hp
