This will start with 'FM' and will be located on your original purchase receipt, or on the side of the product box. By servicing your valve/adaptor at regular intervals, you can ensure that your Forge Motorsport product will last a lifetime.Each service kit varies depending on which product you need it for: Valve service kits ONLY contain replacement "O" rings, piston, and grease. Blow off adaptor service kits contain ONLY replacement "O" rings and bolts. The splitter valve service kit contains a replacement brass piston and spring.   Valves that have O-rings situated on the piston will not come with a piston as the wear is on the O-rings rather than the piston itself.Valve Service Kit Instructions 1Valve Tightening Instructions V3 3Please Note: In line with our policy to constantly review, revise, and improve our product range, the appearance of the product you receive may differ from the one advertised.

Forge Ford Focus ST MK4 280 Induction Kit

Forge

Gains of up to 17BHPBlack powder coating for ultimate protection and durability.  Forge Pleated performance air filter No engine management check lights (EML) Increased air flowLifetime warrantyThis FMINDK37 is the cold air intake system for the Ford Focus ST Mk4 and has been designed to improve airflow in several key ways. It routes the air more directly into the vehicles engine, using an increased diameter CNC mandrel bent alloy pipe. This induction system also improves the airflow by adding our Forge high flow pleated air filter, in place of the more restrictive factory air filter.The choice of air filter was made after many rolling road sessions and data logging test drives. As we have seen many times before with Ford power plants our Forge Hi-Flow pleated air filters gave the best results. The construction and build quality of the filter oozes superior quality and enhances the ST 280s engine bay. Forge Hi-Flow filters are made using a premium quality, high flow, synthetic nanofiber filtration media which is pleated to maximise surface area and in turn increase air flow.The CAD designed, laser cut, and precision folded heat shield is designed to form a barrier between the air filter and radiant heat from the engine. It also helps duct the cold air to the air filter, to help preserve low intake temperatures. The heat shield is designed to incorporate the OEM air duct and fits directly to the standard factory air box mounting points and rubbers without the need for modification.The diameters on this air intake have been carefully tuned to provide exactly the correct quantity of air flow into the turbo charger, ensuring consistent power gains throughout the rev range without any loss of low-end torque, increasing power and enhancing induction acoustics for added character and excitement.We used Performance Remap in Gloucester with their VTEC 4 wheel-drive dynamometer, this was to ensure all our data has been collated independently, The results below speak for themselves, Testing and development took place on a MK4 ST 280 with Mountune STAGE 1 software. The stock dyno pulls gave a base figure of 307 BHP at 5458 RPM, from simply swapping out to the Forge Motorsport Intake in the matter of around 30 minutes, yields of over 17 BHP were achieved.When studying the dyno graph below the peak torque figure does appear to be 5NM below the stock airbox figure however please take note of the 17NM gained from the Forge Motorsport induction kit throughout the midrange.With both the BHP and torque figures held higher throughout the rev range your engine will definitely have the edge and feel more responsive when pushed to its limits. As with all Forge Motorsport products we offer a no quibble lifetime guarantee on all parts of this kit excluding the filter.
