Oiled vs. Dry Filters — Which Is Right for You?

Oiled Filters

Offer slightly higher airflow for maximum performance

Require more frequent cleaning

Must be re-oiled after each cleaning

Long-term reusable design saves money over disposable paper filters

Dry Filters

Provide excellent airflow with minimal maintenance

Easily cleaned with warm, soapy water—no oiling required

Still flow significantly better than OE paper filters

Fully reusable and cost-effective

Both versions deliver superior performance over stock filters while offering the long-term benefit of reusability. Choose the option that best fits your maintenance style and performance goals.

Front set of DOT-compliant lines for an improved pedal feel.

ECS Exact-Fit stainless reinforced brake lines provide more confident and dependable stopping by maintaining consistent brake pressure, long lasting corrosion resistance, and increased protection from failure.

Even when new, factory style fabric mesh lined rubber hoses are prone to expansion under the pressure of hard braking, whether it be highway panic stops or threshold braking at the track. This expansion is even more prominent in aged and weathered rubber hoses. ECS Tuning's Exact-Fit lines are engineered and assembled with braided stainless steel mesh and offer superior expansion resistance and reinforcement. The resistance to expansion creates a firmer pedal, and a more direct pedal feel. The signature red polymer coating provides additional protection from the elements and abrasion common with the constant movement of suspension and braking systems.

ECS Exact-Fit brake lines are engineered in house to comply with DOT (U.S. Department of Transportation) FMVSS 106 standards. All lines are made on dedicated, DOT-compliant brake equipment and each is tested to 3,000 psi before being shipped.

Included in this kit are a pair of custom made ECS Exact-Fit brake lines for the front and rear of your vehicle,
