ISR Performance 3" MAF ADAPTER - NISSAN S13 1989 -1994 KA24DE / SR20DET

The ISR Performance 3-inch MAF Adapter is the standalone adapter that mates a 3-inch inlet cone filter to the factory S13 MAF housing. High-quality aluminum construction, direct bolt-on, sold separately from the cone filter. This is the adapter component from the IS-998PSC/IS-S13MAFADPT complete kit, useful if you already have a 3-inch cone filter and just need the correct adapter for the S13 MAF.

What It Does

Adapts a 3-inch I.D. cone air filter to the factory S13 MAF housing flange. If you've got a quality 3-inch cone filter on hand or you're replacing an adapter that's been damaged, this gets you back in service without buying the full kit.

Critical Fitment Notes

3-inch inlet I.D. filters ONLY. Will not work with the factory airbox, factory air filter, or filters with a different inlet size.

Mounting hardware not included. No mounting bracket, nuts, or bolts in the kit, since the install reuses the factory MAF hardware.

Fitment

• 1989-1994 Nissan 240SX (S13) with factory KA24E or KA24DE MAF
• Nissan SR20DET S13 with factory SR MAF

For a complete filter + adapter kit, see the IS-998PSC/IS-S13MAFADPT kit, which includes a matched cone filter sized for this adapter.

What's in the Box

• 1x S13 MAF adapter (3-inch inlet)
