Eurocode Tuning is proud to introduce our TRUFit Air Intake System featuring Eurocode TRUFit technology.  Our Intake features TRUFit 6 ply, wire reinforced throttle body inlet hose and our own proprietary double layered cotton-gauze dual cone air filter.

The factory air box on the B8 S5/S5 3.0T is a wonderful product, not only does it draw cold air in from the front of the vehicle, it also provides excellent insulation from the heat that is found in the engine bay.  But there are a few restrictions that reduce potential performance, specifically the throttle body inlet hose and the disposable paper filtration system.

To overcome these restrictions, we designed our TRUFIT Air Intake System to replace both the throttle body inlet hose and the paper air filter.  Our design team found that the OEM throttle body inlet hose was very restrictive with its accordion like design and integrated sound muffler.  We chose to upgrade this hose by building a six ply, smooth interior, wire reinforced silicone hose which is very strong and resistant collapse even under vacuum levels many times greater than it will ever see.  Utilizing our TRUFit technology, the hose fits perfectly between the factory air box and throttle body and even uses the OEM clamps to save you money.  With the factory air box being very efficient at drawing in air from outside the engine bay, it also draws in an enormous amount of dust and debris.  The OEM paper air filter is extremely restrictive and its performance deteriorates very quietly with miles in service.  Our TRUFit Drop-in Air Filter has a dual inverted cone design, cotton-gauze synthetic oil filter with extra deep pleats further increasing the filtration surface area.

Features:

• Six ply silicone with a black exterior and red interior
• Wire reinforced to reduce all chances of collapse under vacuum
• Smooth interior throughout providing maximum airflow to the throttle body
• Precise fitment, even when the hose meets the clips on the air box
• Easy, do-it-yourself installation with typical household tools
• Twin layered cotton gauze, synthetic oiled for superior filtration
• Steel wire mesh reinforced to provide strength and resistance to collapse under vacuum
• Extra deep pleats, with a 10-15% increase in filtration surface over other common cotton gauze filters
• Dual inverted cone design with maximum surface area
• Traps particles as small as 5 microns
• 50,000 Mile service interval (with normal use)
• Washable and Reusable
• Increased Horsepower
• Better Fuel Economy
