Technical Notes:

If PRL could recommend an intake system for the 1.5L Turbo Civic Platform it would be their Cobra Cold Air Intake System. However, for customers that do not wish to run a CAI, their Short Ram Intake System is also an option. PRL's CNC machined billet aluminum MAF Housing was designed to provide *factory-spec fuel trims (-4% of factory STFT & LTFT) for optimal drivability and performance. This SRI utilizes a 4" air filter and is available with two different MAF housing choices; a Standard Bore housing and a Big Bore housing. Both housings utilizes the factory MAF sensor, but feature two different diameters and profiles. As mentioned above, the Standard Bore housing is designed to provide factory-spec fuel trims WITHOUT any tuning whatsoever. The Big Bore housing allows a 50% larger volume of air in comparison to the Standard Bore housing, which is why a tune IS required. This larger volume of airflow reduces pumping loss and creates an unrestricted air path to feed the MAF housing with ambient temperature air.

Customers can switch between MAF housings without having to buy another intake system by purchasing PRL's MAF Housing Conversion Kit.

Customers can convert to a Cold Air Intake with their Cold Air Intake Conversion Kit.
