4in Inlet Cone Filter Red 3.5in Long

The 4in Inlet Cone Filter Red 3.5in Long by SPECTRE is a high-flow intake filter designed for vehicle owners and mechanics seeking improved engine breathing and air intake efficiency. This cone-style filter replaces restrictive factory intake components, allowing your engine to draw cooler, cleaner air more freely during acceleration and sustained load.

Engineered to fit most universal 4-inch intake ducting applications, the filter maximizes surface area for filtration while minimizing airflow restriction compared to traditional cylindrical filters. The 4-inch inlet diameter accommodates larger volume air passages, making it ideal for naturally aspirated engines or moderate forced-induction setups where stock intake paths create bottlenecks.

Mechanics and DIY enthusiasts appreciate this filter for custom intake projects, turbo conversions, and engine bay modifications where off-the-shelf solutions don't fit. The bright red finish provides visual engine bay appeal while the compact 3.5-inch length fits tight engine bay spaces, allowing for flexible intake ducting routing.
