FORD FOCUS RS 2.3 ECOBOOST
Increasing the airflow with an aftermarket intake can contribute to exacerbating a whistling sound on idle or light throttle that might not have been previously notified. Caused by air flowing over the OE resonator in the compressor housing the Revo sound suppressor has been designed to help cancel out this whistle, by simply removing the existing Oem piece and replacing it with the  Revo part you are creating a chamber that works as an active cancellation device, eliminating the unwanted sound.

MACHINED HOUSING
Made from aircraft-grade 6061 T6 aluminium the main housing of the sound suppressor has been designed to be a direct replacement for the OE unit. Manufactured to +/-0.10mm dimension tolerances for precise fitment the machined housing has a Viton rubber o-ring to ensure a tight, solid fit. Finished with a laser-etched Revo logo and anodised in black, it's a shame to have to hide it away.
 
SILICONE CAP
The simple yet effectively designed silicone cap has been manufactured using a 4 ply oil-resistant silicone to offer greater longevity.
