It seems expensive for a cold air intake. But it says it recaliblates ecu for better air fuel ration and gives 30+ hp. That seems like alot. Can anybody back this up and how hard is it to install?

 

try researching SRT intake and read up on it.
there's quite a bit of threads on this topic. GL and enjoy!

 

More than Likely you're not going to get 30+ HP out of it, maybe like 20 HP ... But yea I think it's worth it, and the sound is so aggressive and sexy

 

i have the srt on both my gs3 and gs4. i must say that it isn't noticeable on the gs300 but on the gs400 it is really noticeable!

 

glad i didnt get it for my 300, then.
just got the k&n drop in.

 

do you notice any thing different w/ ur GS300 with K&N drop in ?

 

not at all. i havent clocked the mileage yet either-supposedly it should increase mileage.

i got it since i didnt want to spend $300-$400 on a not CA CARB-approved SRT intake. i only have a 300. how much faster can i really make it w/out having to dump tons of $$$ into it? + i didnt want to have to deal with any CEL's or the sort. that's why i'm just a cruiser

if anything, it does breathe more air. and there's no diff in sound when comparing oem to k&n drop in; if anyone says there is, its definitely so little its not worth mentioning.

 

Dynoed 207rwhp. So I say it helps.

 

207? i thought it'd be more than 270hp at the wheels...maybe i dont understand the whole rwhp thing.

 

207whp is more likely from a GS300. if it's from a GS400, either someone pulled 2 plugs out or there is some major clog in the engine

 

Yea those are definitely numbers for a 300 because a 400 or 430 will make about 240 to the wheels bone stock.

 

read the title

SRT, Headers, and HKS exhaust. 207 hp at the wheels on a GS300

 

I' curious... just for testing, did someone ran or made a Dyno test without any filter at all? This way there is not issues of drafting/blocking air into the combustion chamber.

 

Had this installed on my GS400 last week and love it! I don't see how some people say it doesn't do anything. I could tell a very noticeable difference in performance in my daily drives.
