I was curious if anybody recommends cold air intake for b5 audi a4
You think the stock ram air type is better? Considering it is taking in straight air from the grill. And the cold air intake would take air from the warm engine bay...
Is the cold air intake still better?

 

it's generally accepted that aftermarket short ram CAI's don't really increase performance and can actually lower it in some cases. the engine bay is really hot and you would be putting your intake right next to the exhaust manifold which means it is sucking that hot air into your turbos and you are losing horsepower. the stock box is very well designed so your best bet is to get either a new drop in filter or something like the AWE S-Flo that goes inside of your airbox. all a short ram really does is make your turbo sound louder...but you lose horsepower in the process.

 

Thanks
I was thinking that
Prolly go with K&N in the stock airbox
unless there is a better filter anyone recommends?

 

I was thinking about getting an aFe?? good idea?

 

there a waste of money on turbo charged cars the air goes through an intercooler anyways. I just bought a K&n drop in filter and saved myself a few bucks.

 

the reason people get cold air intakes is because either they either have huge turbos and the stock air-box just isn't cutting, and it actually requires an intake it or because the want the cool turbo spool sound to be louder..
so if you just want the sound do the air-box mod, but if you want some sort of performance get a really good heat shield...

good luck

 

i do love the turbo noise and i wouldnt mind better gas mileage so i think i am going to put in a cold air intake.

 

ok cool, get a custom ebay one for cheap with a K&N cone....
and you might consider getting a splitter valve or something so when the spool build up reaches it highest point it goes pshhhht.....now that sounds awesome...and that valve will hold more boost longer...
good luck

 

where would the splitter valve go?

 

were your diverter valve is now...
its a direct bolt-on swap...
