Plastic tends to be a pretty brittle substance. This has been shown on stock turbo inlets as they break over time. This can cause the engine to run rough or not start at all. Knowing this, GrimmSpeed decided to correct this issue with the aluminum turbo inlet upgrades. Made of A380 cast aluminum for durability and longevity, these turbo inlets also have mating surfaces that are CNC machined for a precise and tight seal. Each option is specific for its model and will not only outflow the stock inlet, but will do so without a tune ever being needed. Simple to install and simple to avoid future headaches.

Key Features:

• Seamless airflow - CAD optimized design eliminates OEM air pockets. Supports other power adders and can result in power gains.
• Solid A380 cast aluminum.
• Stock fitment with better overall flow.
• No tuning required.
• High quality breeze clamps and Viton o-ring included in every kit.
• Easy installation.
