This Auction says that this is for the NA fc only. Is that true or is it just somoene who doesn't know what they are talking about? I'm looking some somethign like this for my s4 turbo.

 

This should work on both N/A and turb S4 FC.

 

arent those crap tho anyways i have a n/a and i herd they were crap sorry to to thread jack

 

it'll fit the S4 turbo also.

 

the plate is all you really need, you can hook whatever intake piping you want to pretty much

 

Yeah, from my understanding for the NA the stock intake is one of the best since your biggest road block is the MAF and sucking warm air from the engine bay is no good but on a turbo car i don't think sucking warm air is such a big deal since it is warmed up by compression anyways. plus it will sound pimp with a turbo I'm a ricer at heart :p

 

Yes, you are.
Colder in, colder out...compressed or not.

 

So you can just bypass the intercooler then, right?

 

not a good idea there buddy. wait your being sarcastic. lol

 

no because the TMIC (while is does very little) is what cools the compressed air... however i'm pretty sure it doesn't cool the air down to a temperature below that of the ambiant engine bay temps so I don't think sucking air in from the engine bay is so bad.

 

The stock TMIC does not "do very little". It's quite effective in stock configuration.

Sucking air in from the engine bay is about one of the worst downgrades you can do. Unless you have a large turbo where the turbo itself and intercooler piping prevents you from properly ducting the intake to a cold air source, there is no excuse for replacing the properly designed Mazda stock intake with something that pulls in hot engine bay air. The loss of power is dramatic due to the less dense intake charge.

 

You will notice hot air vs cold air on the stock tmic. It will be less noticeable on full fmic setups, if it all. Some setups with sprayers will cool the charge below ambient even.

 

i notice bit of change like mpg, but i did make some holes and got the vented headlight for the intake

 

I've had K&N Kits on my N/A and it worked great. Is that setup off of ebay anygood? Hows the filter?

 

colder air means more air molecules. simple as that. the the stock snorkel and air filter box on there. sure it heats up, but the air hardly has enough time to heat soak in that thing.
