The new design Stage 2 induction kit that works perfectly with the standard Focus ST250.
Expect to see gains of 5-10bhp compared to the original air box.

Key Features:

• Removes original plastic, restrictive air box
• Adds power, torque, response and driving experience
• Enhanced induction sound and turbo re-circulation noise (dump-valve ‘psssh’)
• Free flowing air filter & optional K&N dry charger filter cover
• CNC MAF sensor boss with AS engraved logo
• Powder coated alloy heat-shield with 80mm cold feed pipe which directs air to bottom of filter
• Adds style to your engine bay
• Easy fitting

Conclusion. It’s easy to fit, looks great, sounds even better, doesn’t cost the earth and can be put back to standard quickly (for warranty purposes)
