AIRTEC Stage 1 70mm Core Intercooler Upgrade for Focus RS Mk1

< Back




Finished in Pro-Series Black for that ultimate sleeper look!

Why do I need a front mount intercooler kit? The original charge cooler kit works o.k. on standard cars but on modified cars with increased boost etc the water temps in the charge cooler can't cope and start to climb to scary levels which can cause your ACT's (Air charge temperature) to rise to over 55+ degree's (on our test they kep't climbing to well over 55 on charge cooler system)  leading to power loss & possible engine damage,by fitting a Front mount intercooler  these ACT's are kept well below the safe 50 degree mark, which in turn will help your engine produce more power safely (please see ACT's results below).

This kit will take you approximately 4-6 hours to fit and can be carried out at home, there is no cutting, grinding or welding & you dont need to turn your turbo housing with this kit.
Kit includes.
Airtec 70m core Focus RS intercooler
Alloy boost pipes
Silicon hoses (please choose colour from options)
Full stainless steel jubilee clips for silicon hoses
Alloy Battery relocation tray with battery clamps
Step by step fitting Instructions
No other parts needed we provide every bolt, nut you will require.
(Please note this kit has been designed to use k&n gen2 or similar and original airbox can not be used) 
Test results taken @ torque of the devil on 31/01/09
(Tested on our own test car, mods were dream science set on race, stainless exhaust with de-cat, gen 2 air filter, uprated actuator and of course huge Airtec front mount intercooler kit.)
Before Intercooler was fitted the car made only 262bhp & 306 lbs/ft
After Intercooler was fitted it made a very impressive 292.7 bhp & 345 lbs/ft torque @ 21psi peak boost, thats 30 bhp just by bolting on this kit!
Act drops (Air charge temperature)
Inlet temp (going into intercooler from turbo) 158 degree's
Outlet temp (coming out of intercooler going to inlet manifold) 25 degree's
Yes 25 degree's 'thats a 133 degree drop in act' simply amazing.
Please remember our car has standard Turbo & manifold and this kit will work even better fitted on cars with after market manifold's and turbo's.
Add a K&N Gen2 Air filter kit for just £269.95 in our combo deal.
