Vehicle Application: 2017+ Civic Type R (FK8) (RHD & LHD models)
PRL's Civic Type-R FK8 upgraded charge pipe kit utilizes smooth flowing, 26% larger inner 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:
Heat-soak reduction: Silicone hose offers extremely low thermal heat transfer properties, especially in comparison to steel or aluminum.
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 PRL track adventures on PRL's shop car. PRL's high-temp, 4-ply silicone with handle the high temperatures of the turbocharger much better than the factory rubber hose(s).
Smooth airflow: Custom molded silicone allows much higher flowing bends than could have with metal tubing.
Optimal fitment: PRL has found that the factory rubbers hoses don't offer the most desirable fitment, especially when paired with an aftermarket radiator. PRL's silicone hose(s) offer even better fitment than factory.
