Direct Port 4PLUS2

Perfect your octane delivery and put racing gasoline expense behind you. Mist distribution is guaranteed so that no cylinder is overloaded or underserved. Tuning is simplified and fluid consumption is reduced.

The block is easily expanded. A total of four main ports are on top. Another, on the far end,  is closed by a removable brass plug. Add an additional straight, elbow, or t-fitting to serve up six nozzles. The most popular four cylinder configuration is one nozzle per cylinder plus another placed after the intercooler for air temperature reduction. Advanced builders have even more options: Spray into the compressor to increase peak air flow or right after it to drop intake back pressure and avoid intercooler heat soak.

Nozzles are exclusive and proprietary to USRT with the industry's smallest orifice size at a mere 125 microns (.125mm). The polymer lines work directly with the same quick-disconnect fittings type used elsewhere in all kits. Our celebrated Tuner's Pressure Gauge is supplied with each kit to facilitate tuning precision. Combine with the tunable AEM FAILSAFE Device to maximize benefits. Spike your brew with nitromethane for instant and safe power gains while you're at it!

Results are well-proven on supercharged 2.0l 8vs, Mk4 R32 turbo, BMW M3 turbo, and more. Any vehicle with a metal intake manifold can be easily fitted. (Plastic manifold solutions are under development now.)

 

Nozzles flow 25 or 45cc at 60psi. These are the smallest and best atomizing nozzles available on the market.
