True Flow is pleased to introduce the True Flow XDI "Xtreme Duty Intake" for universal and late model direct bolt-on applications.  True Flow has taken a unique approach to develop an intake system with ultra high flow, aggressive sound and extreme looks.

Many heavy duty trucks suffer from undersized air filter boxes that choke down airflow to minimal engine requirements.  True Flow replaces the factory air box and restrictive factory plastic tube to increase airflow beyond the engine's capabilities.  The True Flow XDI is offered in a direct bolt-on intake for many late model truck and SUV applications.  Also available is the XDI Universal that can be fitted to most any application including off-road race trucks.

The True Flow XDI is constructed from powder-coated aluminum with direct bolt-on applications including, powder-coated mandrel bent tube and nylon reinforced silicone couplers.  By doing this, True Flow is able to improve horsepower and torque in applications requiring greater airflow than the factory intake is capable of.  This combination not only improves performance but also increases fuel efficiency and has a great intake tone.

A critical part of the XDI intake system is its True Flow air filter.  Unique to the industry, foam air filters have awesome performance capabilities and filtration properties, filtering even the smallest particles.  These incredibly durable air filters are easily cleaned and offer a limited lifetime warranty with excellent performance.

We have the best price around for True Flow air intake systems!  If you want your vehicle to have all the cool, clean air it needs at the lowest price then your only choice is True Flow from Grimm Performance!  You will see horsepower and torque increases!  You will get better gas mileage!  Independent tests prove it!  Grimm Performance provides a 30 day money back guarantee!
