Our intake system fits within the factory air box and attaches with a clamp to the airbox. Our higher flowing air filter systems offer significant improvements in air flow, filtration with up to 2 HP increase over stock. This is especially important with turbo applications as any restriction before the turbo affects power output. The EVP intake filter system is constructed of the finest synthetic filter material which outperforms the OEM while being washable and reusable. Our air filters trap the smallest dirt particles that ordinary cotton-gauze “performance” filters or the OEM’s can’t capture. This product includes our custom Pre Filter which is designed to keep out particles of dirt and sand debris as small as .005″. Our filters run dry meaning no oils or additives are required. Additionally, our Pre-filters add a second level of protection. The woven mesh is specially treated using a proprietary process to repel water. This hydrophobic water repellent process is not sprayed on; consequently there is virtually no airflow loss. Our Pre-filters are used and recommended by top professional engine builders and race teams worldwide.
