PRL Intercooler Charge Pipe Kit for FL5 Type R/DE5 Type S

PRL Motorsports Intercooler Charge Pipe Kit - 2023+ Honda Civic Type R FL5 / 2024+ Acura Integra Type S DE5

Your stock FL5 or DE5 charge pipes are restrictive and the factory rubber hoses expand under boost. When you're making more boost than stock or you're running an upgraded intercooler, your factory charge pipes choke airflow and your rubber couplers balloon. We designed our charge pipe kit to fix that. Our cold-side pipe's larger diameter than stock, which flows more air. Our hot-side pipe's the same diameter as stock, which keeps your turbo spooling fast. We use 4-ply silicone couplers instead of rubber, so they don't expand under boost and they don't melt from turbo heat. If you're upgrading your intercooler or you're making more boost than stock, you need better charge pipes.

Here's Why Your Factory Charge Pipes Don't Work

Your factory charge pipes use rubber hoses that expand under boost. When you're making more boost than stock, the rubber hoses balloon and you lose boost pressure. The hoses also get soft from heat, and if you're running hard at the track, they can melt from turbo heat. We've melted factory rubber hoses multiple times on our shop car. The factory cold-side pipe's also restrictive. It chokes airflow to your intercooler, which means higher intake temps and less power. Our charge pipe kit uses larger-diameter cold-side piping and 4-ply silicone couplers that don't expand or melt.

Larger Cold-Side, Stock-Diameter Hot-Side

We designed the cold-side pipe (intercooler to throttle body) with larger diameter than stock. More diameter means more airflow, which means your intercooler flows better and your intake temps are lower. The hot-side pipe (turbo to intercooler) is the same diameter as stock. Keeping the hot-side pipe stock diameter maintains turbo spool response. If you make the hot-side pipe too big, your turbo takes longer to spool. We kept it stock diameter so your turbo spools just as fast as factory while your cold-side flows way better.

4-Ply Silicone Couplers Don't Expand or Melt

We use 4-ply silicone couplers throughout the kit. Silicone has way lower heat transfer than aluminum or steel, so it doesn't heat-soak your charge air. Silicone's also way stronger than rubber. The factory rubber hoses expand under boost, especially when you're making more boost than stock. Our 4-ply silicone couplers don't expand. They're reinforced with four layers of fabric, so they hold their shape under high boost. Silicone also handles heat way better than rubber. It doesn't melt or get soft from turbo heat.

Cast Aluminum Intercooler Outlet

The kit includes a cast aluminum intercooler outlet piece. It's designed to mate smoothly with your intercooler and our charge pipe. The cast aluminum piece flows better than the factory plastic outlet, and it doesn't crack or break from heat cycling.

1/8" NPT Port for Boost Gauge or Sensor

Our charge pipe has a 1/8" NPT auxiliary port. You can use it for a boost gauge, a MAP sensor, or any other 1/8" NPT fitting. The port's on the cold side of the intercooler, so it's reading post-intercooler boost pressure. If you're not using the port, plug it with a 1/8" NPT plug.

Note: This charge pipe kit works with your factory intercooler and any aftermarket intercooler. We recommend using it with our PRL Motorsports intercooler for optimal fitment and results, but it's compatible with any factory-fitment intercooler. No ECU tuning required. The charge pipes flow better than stock, but they don't change your boost levels or fueling enough to require a retune. If you're already running a tune with higher boost, you don't need to retune just for the charge pipes. Check all your couplers and clamps after installation. Make sure everything's tight and there are no boost leaks. A loose clamp will kill your performance gains. If you're not using the 1/8" NPT port, plug it with a 1/8" NPT plug. Don't leave it open.
