Hi just a quick one any one know if there is any were I can get carbon pref roof fin or know if the 2014 fit the new sti 2015 also any one see any benefits from the intercooler spray only reason I ask is my car seem to run quite a bit quicker and more happy now the tep out side has dropped

Have a look at the perrin stuff they seem to do a fair bit for the new car already.

As for the I/c spray there are diy kits you can add but unless your driving the car hard all the time I personally wouldn't bother.

The turbo likes the cooler air its drawing in from the intake side

Exactly what stants said. Whole idea is cool down intercooler allowing for dense air + more fuel = more power, those I/c sprays are not for constant use.

Thanks mate i understand the principles behind the i/c spray but what I was trying to work out is does this cool it down enough to make any significant difference

Yes it does. Some tests I seen show its about 10-20 bhp increase with fmic sprayd. In subaru case I would say 5-15 bhp because its smaller.

Thanks for the info steve appreciate it bud I will look at getting one then
