This Rajab Racing Developments 'bolt on' intake plenum suits Nissan's RB25DE/DET engines from the Nissan Skyline R32 / R33 GTS GTST. Designed and manufactured right here in Australia, this plenum is the pinnacle of over 30 years of industry experience! Aimed at increasing air flow to the combustion chamber, our plenums equal out the intake runner system to create an even flow of air to the individual cylinders. This helps to maintain even power operation across the engine and enables the tuner to be able to optimize the tune for the best results.

The testing we have conducted at Rajab Racing HQ against a OEM intake plenum, showed a huge change in turbo response with reduction in spool times and a solid overall power gain with back to back results.

Rajab Racing has been making and testing manifolds since the 1990's and have multiple award winning cars using their designs that have withstood well over 1200hp. You are buying a premium product from a respected and trusted name in the automotive world!

MORE INFORMATION:

Our plenums are constructed from a cast aluminum structure, then heat treated to maximize strength and CNC machined for a flawless finish! This allows us to say we have some of the best consistency available on the market today across our product range as every single manifold we manufacture is identical to the first one we ever made, both in terms of internal structure, as well as flow characteristics. 

FEATURES:

• Made in Australia.
• Lifetime Warranty.
• Sleek OEM look.
• 5 x 1/8NPT ports at the back.
• Heat treated Cast Alloy.
• CNC Machined for a perfect finish every time.
• Retains the standard washer bottle and does not interfere with it.
• Large -8AN port at the rear.
• Direct bolt on to Lower runners from RB25DE/DET from R33 Skyline GTS/T.
• Internal intake runner of 85mm to accommodate larger flow from bigger throttlebodies.
• OEM R33 Throttlebody Flange, however there is enough meat to drill and tap your own throttlebody flange holes to suit up to 82mm DBW or up to 82mm Cable Throttlebody, or simply cut the flange off and weld your own.
• Comes with throttlebody cable bracket.
• Comes with remote mount Idle Control Flange to suit R33 Idle Control Motor.
• Hardware and O-ring seals provided - You can use a Cometic gasket in place of the O-ring seals, we just recommend you don't use a rubber gasket as they will blow out under high boost settings. 
• Works with OEM fuel rail and aftermarket top feed fuel rails (we recommend using race works fuel rails with either 1/2 height or 3/4 height injectors which you can find on our website.
• Works in plenty of conversions as it has plenty of clearance.
• Potential to gain 35+hp.
• Eliminates crossover piping which makes servicing easier and provides better access to spark plugs, also lowers intake temps as the piping can now all stay on the driver side away from the hot exhaust or heat of the engine itself.
• We recommend using the OEM throttlebody for up to 600hp and a 72mm for anything up to 800hp, after that we recommend fitting a 82mm Drive By Wire throttlebody to take advantage of the new technology. 

*** We also have a range of Flow matched fuel injectors available in the Fuel System Section of this online shop - these will make a great addition to your intake purchase . Any Injector you can not see please feel free to email/contact us, as we can source them ***
