Rajab Inlet Manifold Top Half - Nissan Skyline RB25 DET R33

Description

The Rajab Racing Developments RB25DET intake plenum was designed right here in MelbourneAustralia, . The Rajab Racing Developments RB25DET intake plenum was designed to increase air flow to the combustion chamber and to equal out the intake runner system to be able to maintain the Evan flow between individual cylinder to maintain even power operation across all cylinders enables the tuner to be able to optimise the tune for the best results. The testing we conducted on the Mainline prohub dyno, testing the RajabRacing RB25DET  intake plenum, was back to back with a common short runner intake plenum and the results were outstanding to say the least. The increase in Turbo response was amazing and reduction in turbo spool was also outstanding.

USEFUL INFORMATION:
Our plenums are constructed from a cast aluminium structure, then heat treated to maximise strength and CNC machined finished, for the best consistency available on the market today, meaning every single one we manufacture is identical to the first one we ever made, in terms of internal structure as well as flow characteristics.These plenums, like the rest of our range are and always will be 100% made right here in Australia.
