Product Description

The Injen HS3500BLK Universal Air Filter Heat Shield is a high-quality accessory designed to improve intake air quality by shielding your air filter from hot engine bay temperatures. Constructed from aircraft-grade aluminum with a sleek black finish, this heat shield helps deflect radiant heat away from the intake, promoting cooler, denser air for better combustion and potentially improved performance. Its universal design fits most vehicles equipped with aftermarket air filters or intake systems that have an inlet diameter between approximately 3.0" and 3.5", making it a versatile option for many custom builds and performance setups.

Installation is straightforward and typically takes about 30 minutes using the included adjustable brackets and hardware. Whether you're pairing it with an Injen intake system or another brand's intake, the HS3500BLK provides an effective thermal barrier that helps maintain lower intake temperatures under demanding driving conditions. Backed by Injen Technology's limited lifetime warranty, this heat shield is a practical upgrade for enthusiasts who want to protect their intake performance from heat soak.
