What do you guys think I should purchase, the K&N CAI or the INJEN CAI for my 07 TL Type S? The K&N CAI is about $300 and the INJEN CAI is $235. I'm not looking too much at the prices I just want the best performance overall. So let me know what you guys think.

Heard the K&N CAI's are supposed to give some decent gains, but I didnt even know they made one for our car?

i just called and found out that they do. heres the link:

it says that it fits the 07 TL Base but they told me they are updating the system and it does fit the 07 Type S as well.

Take this for what it's worth since my opinion is 1-sided, but I went with the K&N - and I'm not disappointed one bit.

I've never had my car dyno-ed, and I've never dealt with Injen either. But with an '04 auto, I can break the tires loose (enough to where traction control kicks in) when the car hits second which I could never do before.

I know on the web site it shows that we are supposed to get either 5 or 6 HP I believe is what they rate it at. I think more than the HP gain, we get in torque.

If I had to say anthing bad about K&N vs. other brands.. I like the "labeling" on Injen and AEM better than the K&N. With K&N you get a little 1"x2" square metallic sticker to put on. The others are a little more creative (but whose looking under the hood much anyhow)

Good luck whichever you decide to get. The gains are worthwhile in my opinion, and the sound is awesome. Gives the car a nice aggressive growl as well.

The AEM intake is the most popular for this vehicle and along with the FUJITA makes the most hp gains. K&N always makes a great product too, however for this vehicle I would get the AEM.

However, PM me if you need any of the intakes.
