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.

All of the tuning in the world is only as good as the weakest link. More boost in your 135/335 is great! But you will soon learn that some of the factory hardware is not up to the task of handling that extra pressure. One of the first things to fail and cause a boost leak are the factory boost diverter valves. This allows boost to "leak" out of the intake stream and a loss of power from the engine. This ECS Tuning chargepipe upgrade includes a blow-off valve in place of the factory diverter valves. The BOV is higher quality than the diverter valves and will exit intake air to the outside instead of putting it back through the turbo system (which will reduce strain on the turbos). This aluminum chargepipe is also much more robust than the stock plastic factory pipe and the connection to the throttle body is stronger, eliminating another failure point of the stock pipe.

Built-in 1/8" NPT ports allow you to run an additional methanol injection kit (bungs included if you don't want use the ports).

This is a complete kit that includes everything you need to replace the factory chargepipe and diverter valves -

The ECS Kohlefaser Luft-Technik (Carbon Fiber Air Technology) intake for the 135/335/535 is a beautifully crafted dual-cone intake with a glossy carbon fiber enclosure. Developed in-house using ECS's chassis dyno and state of the art laser scanning and 3D CAD technology, the N54 carbon airbox is a direct replacement for the stock system. Laser scanning allows ECS to produce a finished product that is a perfect fit to the engine bay. All tubing is also made from carbon fiber with each piece designed for optimal flow. The carbon fiber sandwiches a special heat-blocking fiberglass core, insulating the air box from engine bay heat. All of this combines to produce more power and torque over a wider RPM range - up to 13ft-lbs and 18hp when combined with a Cobb software tune, FMIC, and exhaust. And it looks amazing every time you open the hood.
