ok so i know theres probably a million threads on best intake but looking for an instant answer... but im looking at either the dejon or k&n sri for my stock '09 tc. im looking at ordering..
1) either k&n or dejon sri intake
2) forge bpv
3) dejon upper charge pipe
4) bad-mab catless dp
5) trifecta tune
--question is...1) dejon is a bit cheaper so will it sound as good as the k&n with the bpv?
2) how do i know when to replace the spring in the bpv for my different power levels?
3) is the lower charge pipe necissary to change out?
-sorry i added another thread to the never ending list but thanks for yalls help!!

 

1. The sound should be too similar to notice a difference between the two. The k&n has been proven to skew fuel trims the least out of the two and will be easier to tune for.
2. Just use the spring that the tuner recommends. Are you going through a dealer or dealing with Vince directly? I've seen people use both springs with the same results.
3. No it's not necessary, but the factory plastic is prone to breaking and leaking. My advice is to save up and replace the fmic and cp at the same time. You get better deals buying them in a package and you don't have to worry about it breaking.

Hopefully someone can help you out a little more with the bpv spring as I have no experience with it.

 

I'd say k&n it just installs so much more securely than anything else Iv seen so far.

 

KN intake for sure, don't even think twice about it. Badmab downpipe as well, for 135 shipped you'd be retarded not to get one. Forge bpv, and the uppercharge pipe are not needed, I would save for a treadstone intercooler the tr8. When you get tuned with trifecta or hp tuners w/e eventually your intercooler plastic endcaps will blow like mine did.

 

sweet thanks huys and ok k&n it is then! and no bpv? does the forge and factory one sound the same?

 

Once you get the kn intake, it will make that sound. Forge bpv and chargepipes you wanted will be like 300$. Instead get an intercooler.

Here is my car with just a kn intake. go to like 37 seconds.

sweet and thats all with just a k&n?!? and ok intercooler it is instead of the piping then and the catless dp

 

Yep, that sound is just with KN intake. catless downpipe, intercooler and then a tune. You'll be good wiht at least 300whp and 350 wtq.

 

yea the KN intake makes your hear the turbo so much better, i was blown away by the difference from stock lol

 

yeah man it sounds great thats definitly on the way then.. quick question what did that catless dp do to your gas mileage on just putting around town or to work? was it reasonable change or what
?

 

Didnt notice anything as I got tuned a week after. Probably not much of a difference though. Once I got tuned I got better gas mileage.

 

I remember those commentators. That **** cracked me up for days. There's another video, right?

 

id go with K&N heres my car with it cobalt ss/tc K&N intake - YouTube

 

You gotta let it get out of cat warmup mode first.
