ISR Performance Intake Kit - Nissan SR20DET to suit slip on housing

The ISR Performance Intake Kit is a turbo-specific intake setup for SR20DET builds running an upgraded turbo with a slip-on compressor housing, like the Garrett RS3871 or GT2871R. Includes an aluminum intake pipe, Z32 MAF bolt-on cone filter, and the silicone couplers and clamps to connect everything cleanly. Precision-engineered to mate the larger turbo inlet to a Z32 MAF in one clean package.

What It Does

Upgrading the SR20DET turbo to a slip-on-housing unit like the RS3871/GT2871R changes the compressor inlet diameter, which means your factory intake won't fit anymore. This kit handles that transition: it routes from the larger turbo inlet through the right coupler sizes back to a Z32-style MAF, with a quality cone filter on the MAF inlet. Designed specifically for this turbo and MAF combination, so the fit is right out of the box.

Fitment

• SR20DET builds running a slip-on compressor housing turbo (e.g., Garrett RS3871, GT2871R)
• Builds running a Z32 MAF (this kit is sized around a Z32-style MAF flange)

Will not fit: Stock SR20DET turbo with factory compressor housing, builds running an S13/S14 MAF instead of Z32 MAF, or any turbo with a different compressor inlet diameter than the slip-on RS3871/GT2871R family.
