KEY BENEFITS:

• Make an easy 280-290kW with a custom tune

• Simple and reliable cooling of intake charge

• Run higher boost levels more safely

• Up to 150°C reduction in intake temps

• Tough appearance of a front-mounted intercooler and chromed intake piping behind the front bumper

• Comes with a lifetime warranty

WHY

Harness the full potential of your L67 supercharged V6 Commodore with this unique air-to-air intercooler adaptor plate.

Designed and manufactured in Australia through an intensive 18 month development process, our air-to-air intercooler adaptor plates offer an extremely efficient, reliable way to reduce intake temperatures; resulting in higher air flow and shorter lag time than some other forms of intercooling.

WHAT

Our new air-to-air intercooler plates are cast from automotive grade alloy and feature a 70mm inlet and outlet for maximum airflow (perfectly matching our 69mm ported throttle body), which is precision machined for perfect fitment and finish.

The plate is 52mm tall and fits between the factory blower and the blower manifold, clearing all obstacles within the standard engine bay; allowing for proper under-bonnet clearance.

Testing has shown intake temperatures to drop by as much as 150°C by using our adaptor plates, allowing you to run more boost, more safely - meaning more power and torque!

In fact, our testing has shown that it's easy to make between 280 and 290kW, simply through fitting our air-to-air intercooler adaptor plates together with a tune. This is over 65kW more than you could hope to make in a non-intercooled L67 application.

HOW

Used in conjunction with a front-mount intercooler, the adaptor plate receives the hot air from the supercharger, cycling it through the front-mount intercooler and back into the intake manifold mounted below. It's a simple, efficient and reliable intercooling option.

Fitment of the air-to-air intercooler adaptor plate is simple for a general mechanic or the more experienced DIY enthusiast in the home garage; however a custom tune of your vehicles ECU will be required.

We offer an optional fitment kit to make the installation of our L67 air-to-air intercooler adaptor a breeze, including all the bits you'll need to get moving. However, if you're planning a custom installation, you won't need to wear the additional cost for parts you're not going to need.

GET MORE

Our L67 air-to-air intercooler adaptor plates really are the gateway to supercharged V6 performance never before known.

With an easy 280-290kW achievable with the adaptor alone, 300kW+ is possible with further modifications and porting.

Originally developed for demanding race applications, K&N's Premium Wrench-Off Oil Filter has become a favourite among consumers for its durability and easy removal. To satisfy the demands of racers, these oil filters have many features over and above the requirements of most vehicles. These features include but are not limited to the use of thicker canister walls for extra strength and durability which reduces the risk of damage from loose rocks and debris, a drilled hole on the nut to provide for safety wire attachment and the use of a resin impregnated cellulose filter media which allows for higher flow rates while providing outstanding filtration.

Key Features: 

• Resin-impregnated filter media traps 99% of harmful contaminants.
• 1 inch exposed nut designed for easy oil filter removal.
• Heavy duty construction for extreme conditions.
• Anti-drain back valve (where applicable) eliminates dry starts, prevents oil from draining back into crankcase during engine shutdown.

Vehicle Fitment Guide

These Mace MLS (Multi-Layer Steel) head gaskets are comprised of five layers of steel. The outer layers are an embossed viton coated stainless steel providing a superior seal with excellent rebound characteristics and corrosion resistance. MLS head gaskets reduce bore distortion and withstand extreme cylinder pressures. These can be used as standard replacement head gaskets but are more suited to higher calibre builds.

A surface finish of 50 RA (roughness average) or finer, is recommended on the head and block for a proper gasket seal. Anything rougher may conflict with the gasket design.

Specifications:

• Bore size: 3.84''
• Thickness: 0.066"

Contents:

• 1 X Cylinder head gasket set

Vehicle Fitment Guide

Notes:

• The image is for illustrative purposes only.
• It is highly recommended copper coat is used when installing these gaskets.
• Standard bore size is 3.80" so ideally, these gaskets would be more suited for oversized bores. However, they are still compatible with standard size. We have other listings for MLS gaskets that specifically suit standard size.

Now have the peace of mind for your LS V8 with our very own, designed in house, Mace Engineering LS trunnion upgrade kit. These trunnion kits replace the factory LS rocker internals that are prone to failure when exposed to extended levels of high rpm, high valve spring pressures and amplified rotation from high-lift camshafts. The OE needle bearing housings can begin to separate from the rocker arm when exposed to these conditions, gradually spitting out all the needle rollers which in turn results in a catastrophe.

Our kits are engineered to provide maximum durability and stiffness in the harshest environments whilst still being super affordable for all enthusiasts. Extra security measures have been taken with the use of extended width trunnions with snap-ring grooves instead of the bearing housings only relying on a press-fit type fixture. You can now rest assured these bearings will hold their ground and truly enjoy the exhilarating feeling your LS V8 delivers.

Contents:

• 16 X Rocker arm upgraded 8620 hardened steel trunnion
• 16 X High tensile re-useable rocker bolt
• 32 X Rocker arm reduced friction heavy duty bearing
• 32 X Rocker arm retaining ring

Note: A shop press will be required to install the new trunnion kits. We can also provide this service for a small fee.

Stage 1

This cam is designed for use on totally stock heads and stock components up to 6000 rpm. It is recommended to upgrade valve springs to increase performance and allow shifting over 6000 where peak power is made. PCM programming required. Expect gains of 26-37kW depending on your car's current configuration.

Stage 2

This cam is designed for supercharged or nitrous applications on ecotec and L67 bottom ends. It produces the highest power and torque figures than any cam grind currently available with stock heads. An even smaller pulley can be used compared to CAM604. Peak power is 200rpm higher than CAM604. Upgraded valvetrain is mandatory (cam packages available through another ad). PCM programming required. Expect gains of 30-45kW depending on your car's current configuration.

Stage 3

This cam is not for the fainthearted! CAM606 was developed to maximize the HP of an L67 in an all out build i.e stroked, balanced, blueprinted, etc. CAM606 requires ported heads with machined valve guides and a complete valvetrain upgrade. Given the base circle diameter varies between lobes custom length pushrods are also required (cam packages available through another ad). PCM programming essential. No other cam makes the power of this cam in a 3.8L, period. Idle is similar to CAM605 with roughly 13 inches of vacuum. Expect gains of 40+kW depending on your car's current configuration.

Head bolts play a vital role in the sealing of the combustion chamber, oil/coolant channels and ambient air. Therefore, we recommend our Mahle cylinder head bolt set for the task. Having met and exceeded OEM specifications, these quality bolts are suited for standard and mildly modified applications. These are torque-to-yield (TTY) bolts which means they are designed to be tightened past their elastic limit, guaranteeing high and uniform clamping forces. Other benefits include pre-applied sealant to the threads eliminating the use of thread locker and no-retorquing is necessary after correct installation procedures have been followed.

This head bolt set suits Holden vehicles fitted with Ecotec L36 and L67 Supercharged V6 engines.

Contents:

• 16 X Head bolt

Vehicle Fitment Guide

Notes: 

• When torquing up bolts, an accurate torque wrench or angle gauge will be required to achieve correct clamping forces.
• Please follow the torque specifications as recommended by the service manual.
• TTY bolts are only to be used once due to permanent elongation and safety concerns.

This high calibre bottom end gasket conversion kit is intended to service the bottom half of the engine block; essentially everything under the cylinder heads. These Mahle gaskets are synonymous with uncompromising quality and durability whilst meeting all relevant OEM specifications. You won’t find a finer sealing product.
