This is a special hose developed together with Nordic Tuning! The hose is fitted to the mass air flow sensor in place of the original air filter box. It is then routed through the hole behind the right-hand headlight and down into the space behind the bumper / right-hand fog light. An open air filter is then fitted in that position. This is the best solution for getting cold air to the engine, but bear in mind that the air filter may need cleaning more often, and that the filter should be fitted with a guard against water spray in front of it. The filter is rated for power up to: 310 hp ITG was probably the first company to make a durable, high-performance foam air filter Why use a foam filter? Compared with paper and cotton filters, a foam filter gives the best possible performance on the following important points: Maximum air flow The ability to let air pass through the filter without causing a large pressure drop. Effective cleaning The ability to stop a very large part of all airborne dust, so the engine is supplied with clean air. High dust tolerance The ability to absorb a large amount of dust without impairing the air flow. Items included in this kit: 1. Steel-wire reinforced hose between the air filter and the mass air flow sensor 2. ITG foam air filter, 310 hp 3. Hose clamps
