The Injen IS1820P is a polished short ram intake built for the 1991-1999 Mitsubishi 3000GT V6-3.0L, and the manufacturer says it fits with no tune required. Its core is a mandrel-bent 6061-T6 aluminum tube designed to keep airflow on a smooth path, paired with a fully serviceable Injen SuperNano-Web dry filter. The compact short ram layout is meant to fit even tight engine bays.
The manufacturer cites dyno-proven gains of up to 6 HP and 8 lb-ft of torque over the stock setup, and that figure is the one to weigh against the price. Owners on user forums often doubt the larger 7-10 HP numbers quoted for ram intakes on this car and report that a short ram and a cold-air setup differ little in output or noise. The case for this kit is a complete, polished, lifetime-warrantied system from a single manufacturer, not an outsized power claim. Injen backs it with its Limited Lifetime Warranty.
For a non-turbo 91-99 3000GT owner searching for a polished short ram intake, owners on user forums say the kit includes the intake pipe, silicone coupling and hardware, and that the tube replaces the center section of the stock rubber intake hose along with the elbow, adding a larger filter and adapter. Forum reports vary on exactly which section it replaces, so compare the stock hose to the new tube before cutting or removing anything. Turbo VR-4 applications should be confirmed with the manufacturer before ordering.
The manufacturer states this intake is built to fit the 1991-1999 3000GT V6-3.0L with no tune required.
The manufacturer specifies a fully serviceable Injen SuperNano-Web dry air filter, so it can be cleaned and reused rather than replaced on a fixed schedule.
This kit is sold for the non-turbo V6. Application information for turbo VR-4 models varies across sources, so confirm fitment with the manufacturer before ordering for a turbo car.
The manufacturer lists an Injen Technology Limited Lifetime Warranty on this intake system.
Owners on user forums describe this as a bolt-on swap that replaces the stock rubber intake hose section and elbow, and they report that the kit ships with the tube, silicone couplings, clamps and hardware needed for the swap. Before you start, lay the new tube against the stock hose to confirm clamp positions and clearance around the throttle body and MAF sensor. Check the installation instructions included with the kit for the exact sequence, and confirm that the filter is seated and sealed before you drive.
