Well I finally bought my first two MACE products. 25mm Manifold Insulator 12mm Plenum Spacer Installed them on Saturday afternoon. Didn't take me too long, started at about 2pm and finished at about 5pm (considering I dropped one of the Fuel Rail spacers onto a ledge on the trans and spent over an hour and a half looking for it, and then had to jack the car up and reach under and get it). so: TIME TO INSTALL: 1.5 hours INSTRUCTIONS: Very comprehensive and easy to follow, fantastic! I wasn't confused about anything. CUSTOMER SERVICE: Steve at MACE is a very helpful and very pleasant bloke. Very easy to deal with and get along with. Very Very impressed! RESULTS: A+ Been driving it around since Saturday and I have really noticed the difference, low end torque has really increased, it climbs the revs alot easier and faster, and really feels like it's breathing and wants to move. I'm starting to feel a little kick into the seat, which will be increased as I further modify the engine in the future. The torque band really does feel like it's throughout the whole rev range, the main power of the motor kicks in low, and it really helps it get moving. For such a simple mod, with my future plans in mind, this is really the start to a kickass budget V6 setup that will really put out some good figures, times and driveability. PERSONAL TOUCHES: I wasn't a fan of the wood colour the spacers came with, so I sprayed them with 3 coates of chrome paint (High Temp Proof of course). Then carefully sanded back the paint on the face surfaces (top and bottom) See Below: All up these are fantastic products from a fantastic company. One I think all us car enthusiasts should back, because with loyal support and products of this calibre already, things can only get better in the future. Very proud to now use MACE products. A+ to Steve and the team at MACE!
