The only drawback is the factory inlet tube from airbox to the turbo itself, that is where ETS comes in to save the day. This kit replaces a 100% of the factory inlet tube and converts the filter from 2.5″ to 3.0″ for even better flow. This is the ONLY intake modification you should be making on your Focus RS!

• Direct Bolt On
• Full 3.0″ Design
• Utilizes Factory Airbox
• High Flow ETS Filter
• Wrinkle Black Powder Coat Finish
• Fits with factory engine cover
