PRL Intercooler Charge Pipe Upgrade | 23+ Civic Type R FL5, 23+ Integra Type S DE5

PRL's charge pipe upgrade kit utilizes a smooth flowing, larger diameter cold-side for increased airflow and factory diameter hot-side outlet to aid in turbocharger spool. 4-ply silicone couplers are used throughout our design for a couple of reasons:

1. Heat-soak reduction: Silicone hose offers extremely low thermal heat transfer properties, especially in comparison to steel or aluminum.

2. Strength and rigidity: The rubber hoses used from the factory are known to experience expansion, which worsens as boost is increased. In time, the rubber construct weakens, causing increased likeliness of a boost leak. Also, we have managed to melt the factory rubber hose a handful of times during our track adventures on our shop car. Our high-temp, 4-ply silicone with handle the high temperatures of the turbocharger much better than the factory rubber hose(s).

3. Smooth airflow: Custom molded silicone allows us to offer much higher flowing bends than we could with metal tubing.

4. Optimal fitment: PRL have found that the factory rubbers hoses don't offer the most desirable fitment, especially when paired with an aftermarket intercooler. Our silicone hose(s) offer even better fitment than factory.
