Show original supplier description

The Attack 4000-40T is a dry nanofiber air filter engineered to provide enhanced engine protection and performance for select classic vehicles. Its core feature is the proprietary Dry Nanofiber Technology, which allows for maximum airflow while trapping debris at a submicron level. This advanced filtration helps to extend engine life by reducing wear on internal components. Unlike oiled filters, this dry filter ensures no oil contamination of sensitive sensors. It is also washable and reusable, requiring only soap and water for cleaning, eliminating the need for harsh chemicals. This combination of performance, advanced technology, and reusability makes it a compelling upgrade for enthusiasts seeking both power and protection. This air filter is specifically designed to fit 1970-1975 Chevrolet Camaro models with 350 V8 engines, and 1970-1973 Corvette models with 454 or 350 engines. Additionally, it is compatible with 1970-1984 Camaro models equipped with 402, 350, 305, or 5.0L engines. Please measure your existing filter before purchase to ensure compatibility.
