We understand that copious controversy circulates through the car scene when it comes to modifying the SIDI V6. With most unfortunately agreeing the gains to dollar value are minimal and after all, what’s the point of enhancing a V6 when it’ll never beat and sound like a V8, right? Well, with the extensive research and development we have poured into performance upgrades for the Australian built SIDI V6 motors, we can safely say we now have a unique range of parts that will prove a world of difference when it comes to performance and driveability.

We have packaged these niche items in such a way that they’re financially tasteful for V6 enthusiasts of any budget. Be it a petite or limitless one, we can assure you the difference will amaze.

 

Key Features:

  • Design registered manifold insulator improves bottom end torque and provides a cooler charge air temperature.
  • Plenum spacer improves air distribution between each cylinder while further reducing heat soak.
  • Mace throttle controller removes the delay in throttle response.
  • 20% underdrive pulley kit improves engine acceleration by reducing the parasitic losses the engine accessories pose across the entire rev range.
  • Orssom OTR maximises performance by optimising the engine’s breathing capabilities and further increases top end power and torque while providing that growl under hard acceleration that everyone loves.
  • Mace cams transform the factory exhaust note into one that screams grunt the whole way down the drag-strip. Given the nature of our cams, fuel economy should still remain quite sensible and power is limitless due to the linear torque curve.
  • 35-45rwkw expected gains.

 

Contents:

  • 1 X 12mm manifold insulator kit
  • 1 X 6.35mm plenum spacer kit
  • 1 X Mace throttle controller
  • 1 X Powerbond power pulley kit
  • 1 X Orssom OTR
  • 4 X Mace camshaft

Vehicle Fitment Guide

 

Notes:

  • A dyno tune is required to achieve the most gains and ensure safe operation of your vehicle.
  • Balancer removal tool is required with this package, which can either be purchased or loaned out through other listings.
  • Please double check under-bonnet clearance before purchasing this package as we have found in the past that this package will not fit all models with LLT’s. If this is the case, we can supply a 6.35mm insulator instead for extra clearance.
  • Quoted power figures are approximate and may vary depending on set-up and many other factors.
  • Further gains are possible with our package through upgraded diff gears, a full exhaust system where applicable and forced induction.
  • Performance valve-springs are available through another listing if the motor will be revving past the factory rev-limiter.
  • We recommend 98 octane fuel to be used after fitting of this package.
  • More detailed information of each performance part can be found through their respective listings.
  • This package isn't concrete and we’re more than happy to put together a custom package if desired. Please contact us for assistance.

Not great at cooling
Size: Queen (2 Count), Color: Original White (Cooling)
Each pillow cover has 2 sides, one marked for cooling, and the other a different fabric. The cooling side is about the same effectiveness as having a silk or satin pillow cover. It's only cool when you first touch it. The cooling side doesn't seem to absorb or wick moisture, so if you are sweaty - it keeps the moisture in place. You'll definitely want a regular pillow case over the pillow cover. In fact, if you suffer from night sweats, the non-cooling side is actually more comfortable. The pillow fill is ample, and simple to squish around for more support for your neck, etc. Think bean bag. But it will retain your impression after use. I find I need to do as I did when I had down pillows - give it a few good shakes in the morning when I make the bed to get it evened out for the coming night. In all, it is a well-made and comfortable pillow to sleep on, but it does not excel in cooling.

excellent pillows i bought two sets!!
Size: Firm Queen (2 Count), Color: Original White (Cooling)
I ordered these for my son who has neck issues and has gone through so many pillows trying to find one that he liked. They’re heavy, so i was worried that they might be “too” heavy to be able to sleep on comfortably, so I ordered a second set, one firmer than the other (just in case) and gave him a set for Xmas and he loved the first set so much without even trying the less firm ones.He also needs the cooling factor and these offered that, too. They are filled with pieces of memory foam (tons of it) and each pillow can be modified by removing some of the foam. The covers are beautiful, high quality fabric with a zipper so ts easy to remove or replace the foam pieces. The size is perfect and they keep their shape. I kept the second set i ordered rather than returning them and i love the pillows. I actually modified two by removing some of the foam pieces. I kept the foam pieces in a zippered pillow protector and i can always adjust mine when or if i need to. 1000% love these.

The Perfect Firm Pillow l
Size: Queen (1 Count), Color: Original White (Cooling)
It is everything it claims to be, cool, comfortable and strong. I got this for my husband first, he loves it and then got one for my son, he uses it to support his knees and has been sleeping much better since then. They both needed a firm pillow that is not super soft, firm but not achy. Finally found the perfect one.

It works! Quality pillow.
Size: Standard (1 Count), Color: Original White (Cooling)
This does actually provide a cooling effect, and it's very comfortable! The accompanying literature is helpful too. I believe this to be a quality pillow for the price.

Most comfortable pillow I’ve ever slept on
Size: Queen (1 Count), Color: Crescent White(cooling)
This is the most comfortable pillow I have ever slept on. It doesn't mash down like other pillows. Cradles my neck perfectly plus it’s cool. I broke my neck a couple of years ago and this pillow feels very good and comfortable. Definitely recommend to everyone. Ive used it since May and it’s retained its shape.
