Offering increased flow for improved top-end power potential without sacrificing mid-range, the Xcessive Manufacturing 20B Lower Intake Manifold is a bolt-on replacement for the standard Cosmo lower intake, featuring four secondary injector ports which makes beefing up your fuel supply an easy task. As a package, each manifold is supplied with a Radium 6-Port Secondary Fuel Rail Kit which is a perfect match & another great upgrade.


Another major improvement the Xcessive lower intake offers over the OEM manifold is improved front to rear balance of flow which is especially important at higher boost levels. With the Xcessive intake featuring matched flow rates for each runner, you are able to take advantage of improved & most importantly consistent airflow which results in higher horsepower and less chance of your engine leaning out at high RPM.

For those looking to carry out a 20B engine conversion, this short version Xcessive lower intake is 38mm shorter than the factory Cosmo lower half which assists massively with bonnet clearance.

- Direct bolt-on replacement for the Cosmo 20B lower intake

- 6 14mm injector ports makes increasing fuel supply easy
