 Hello all. I found this while I was looking for what kind of air setup I want. Hopefully it can help you guys/gals out.

Well after the success of the Header test we have decided to go ahead and do the intake test as well. First off i want to thank a couple of companies for getting us out their intakes: Injen, F5Air, K&N and Scion, oh wait we had to buy the K&N's and Scion charged for the stock air box. Bastards.

I also wanted to thank Leh for staying late with me to see what is what on the Intakes for the tC, and taking the pics. (for those who were waiting for the out come it was Leh's fault but don't get too mad at him)

Any way on to the Test. Our tC is pretty much stock with the addition of the Alfaworks Header that is in place and a B&M short shifter which does nothing for horse power.

Sooo here we go.



First up the stock airbox
Notice the did in Air Fuel on the top end so there is some more power to be had with the stock box using an emanage or even a S-AFC



Second up Stock Air Box with Drop In K&N filter. We left the charcoal thing in as well
This one was an absolute bummer IMO. It lost HP but the air fuel was good.



third K&N Typoon intake
The air Fuel got a little funny on this one. could be the cause for less HP than the others. With the cost of the intake I think your money would be better spent else where.




Forth Injen Cold Air
What can I say about this one it made the most horsepower the Air Fuel line was very clean in fact with an SAFC or ported T-Body could see somewhere in the 165 Range. Over all I am very impressed with this intake.



Fifth Injen Short Ram
We also tryed the short ram Injen Intake. but the hood was open so im sure under street conditions it would be lower do to heat soak. and the Air fuel went nuts around 5300. sense you can't buy just the Short Ram it is totally pointless to not install the Cold Air Section.




Sixth the F5Air Intake
The air fuel did the same thing as the injen short ram so im not sure the R&D was done on this kit as far as fuel tuning. the numbers are good and with a little tuning im sure it could be improved.




Now as far as the install goes i must say that the F5 was the easiest to install but after 3 intakes i think it was just practice.

So the overall winner was Injen and if anyone would like me to lay a graph over a different competitor please just let me know which two you would like to see.

 Remember that the scavenging of the aftermarket header in the car they tested will effect A/F ratios as compared to how it would run with a bone stock motor and intake only. Granted, it may not be much, but there will still be a difference.

I purchased my K&N Typhoon when I first bought my car and wouldn't trade it for anything. The 3-4 hp difference is not going to be felt and won't do anything to your 1/4 time.


Complaining is futile when you supported the victory.
