Product Description

The Injen HS3500P Universal Polished Air Filter Heat Shield is designed for enthusiasts looking to protect their intake system from excessive engine bay heat while adding a clean polished look under the hood. Compatible with most aftermarket intake systems that use performance filters with roughly 3.0" to 3.5" inlet diameters, this heat shield helps create a thermal barrier that deflects radiant heat away from the air filter. Cooler intake air can support more consistent performance during spirited driving and reduce the effects of heat soak during long idling or back-to-back runs.

Constructed from polished aircraft-grade aluminum, the HS3500P combines durability with style. Its adjustable brackets and included hardware allow for a flexible fit across a wide variety of intake setups, making installation straightforward for DIYers and professionals alike. Whether paired with an Injen intake or another brand's system, this universal heat shield enhances intake efficiency and contributes to a cooler, more reliable performance environment under the hood.
