This intake is designed for combinations that are looking to make peak power between 6000 and 8000 rpm. Boosted engine combinations are actually more reliable making peak power in this higher RPM range compared to making peak power around 6500 rpm like most stock style intakes, provided the valve train is engineered properly.

Looking For An LS2 Intake Manifold? What You Need To Know
The LS2 intake manifold is certainly a popular choice for car enthusiasts across Australia. Many people believe that all six litre LS engines are LS2s and therefore they need the LS2 intake manifold for their own car project. This has resulted in other options sometimes being difficult to come by, but the good news is that Malex Motorsports has you covered, both for the LS2 intake manifold or any alternative you might need.
Malex Motorsports stocks LS2 intake manifold options from the best manufacturers in the business but we also carry the manifolds that you’ll need for L76, L77 and L98 engine projects. These are all six litre gen IV LS series engines that were released in the Holden Commodore and Holden Statesman/Caprice here in Australia.
The main difference between an LS2 and the other three engines mentioned is in the cylinder heads which feature cathedral shaped inlet ports whereas the others have rectangular inlet ports. On this basis, it goes without saying that you need to make sure you have the right manifold for your engine’s design.
The features are slightly different between the LS2 intake manifold and some of the other options, too. The L76 and L77 both feature active fuel management (AFM) or displacement on demand (DOD). The newer L77 is similar to the L76 the main difference being flex fuel capability, meaning that the engine can switch between E85 (85 per cent ethanol) and unleaded fuel.
The L98 engine, meanwhile is similar to the L76 and L77 but does not feature AFM or flex fuel.
So why has the LS2 come to have such a towering reputation? The LS2 was GM's performance 6-litre engine and was only released in HSV (Holden Special Vehicles) in Australia. It was later replaced by the LS3 engine which is a 6.2-litre but not before it had become so common to the Australian environment The LS3
A LS2 intake manifold can be difficult to find now as they aren't interchangeable with other 6 litre LS engines, and being exclusive to HSV models a limited number of LS2 engines were released in Australia. Thankfully, Malex Motorsports has you covered.
