ISR Performance Intake Kit - Nissan RB25DET Swapped S13/14

The ISR Performance RB25DET intake kit gives a swapped S13 or S14 240SX a clean, properly routed intake for the factory RB25 turbo. It is built around the engine position set by the ISR RB swap mounts, so the pipe, filter and MAF adapter land where they should in the S-chassis engine bay instead of requiring you to cobble together generic tubing.

Why run a dedicated swap intake

An RB25DET dropped into a 240SX sits differently than it did in the Skyline, and the Skyline airbox and ducting rarely survive the move. A purpose-built intake pipe keeps the mass airflow sensor positioned correctly, supplies the stock turbo with a filtered air source and gets rid of the mismatched hoses most swaps end up with.

• Aluminum intake pipe sized for the factory RB25 turbo inlet
• MAF adapter so the stock sensor stays in the system
• T-bolt clamps on the main joints, worm clamp where appropriate
• Open-element air filter included

Compatibility

Nissan 240SX S13 and S14 with an RB25DET swap using ISR Performance swap mounts and the factory RB25 turbocharger. Engine placement from other mount kits may change the routing, so this kit is intended for the ISR mount setup.

In the box

• 1x aluminum intake pipe
• 3x T-bolt clamps
• 1x worm clamp
• 2x couplers
• 1x air filter
• 1x MAF adapter

Install notes

Confirm the swap is on ISR mounts before ordering. Tighten the T-bolt clamps evenly once the pipe is seated so the couplers do not walk under boost.

All ISR Performance products are designed for off-road use only.
