Mustang K&N Performance Injection Kit Speed Density 5.0L 1986-1988
K&N Performance Injection Kit for 1986-1988 5.0L Mustangs with Factory Speed Density.
K&N Performance Injection Kits contain a high flow K&N air filter with uniquely designed adapters. This creates a radius entry allowing the engine to ingest air with less restriction compared to the factory intake system. These kits are street legal in all 50 US states.
K&N air intake systems replace your vehicle's restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. More air means more usable power and acceleration for your car or truck. The filters on these kits are washable and reusable. Most of K&N's intake kits are relatively easy to install using tools commonly available.
