AIRTEC Motorsport 2.5-inch Big Boost Pipe Kit for Focus Mk2 ST and RS

Technical Data

The AIRTEC Motorsport big boost pipe kit is a must for all remapped RS, everything you need is included in the kit. ATMSFO55

Features:

• Hot side (Turbo to Intercooler) is made from 2.5″ light weight alloy and connected with 5 ply silicon hose joiners.
• Cold side (Intercooler to throttle body) we went for a 1 piece 2.5″ silicon hose, this means you have NO joins and can add to extra flow and increased power. Available with or without dump valve outlet.

Will fit With the following Intercoolers:

• AIRTEC
• Pace
• Pro-Alloy
• Forge
• Ford OEM

Our 2.5″ hard pipe upgrade removes Ford’s 2.0″ restrictive boost pipes. We saw gains of 11.8 bhp & 9 lb/ft torque increase’s over the standard Ford pipes and these gains were achieved by simply bolting on the kit.

This kit is designed for BIG BHP Focus RS’ and will work best on 375bhp and over, was tested on our 400bhp demo car.

Please note: 

• For Focus ST 225 – MUST Be fitted with 2.5″ outlets on intercooler. Stock ST is 2″.
• Will NOT fit Focus ST Stage 1 or 2 intercooler but will fit Focus ST Stage 3 intercooler.
• When fitting, the hose must be angled a certain way to avoid contacting the plastic supports on the radiator 
• To gain further clearance against any sharp edges on the radiator, we recommend trimming the radiator’s excess plastic. Please see fitting note here: COLD-SIDE-BOOST-HOSE-FOR-FORD-FOCUS-ST-AND-RS
