Induction / Air Filter / MAF

TTDA Air Filter

www.modshack.info

TTDA stands for 'Twin Tube Dynamic Airbox'. This is a custom made, hand-built air filter. It consists of a K&N air filter inside a heat resistant housing. It is available in different colours and materials. Highly recommended... you can take my word for it, I've been through quite a few air filter kits.

Previous Air Filters

High Quality Aircraft Grade Neoprene Hose

This is the best material I've found so far to use on any induction kit. It has great qualities such as heat resistance and a spring like nature which helps when using it in awkward areas in the car. It's a great compliment to the above TTDA air filter and is also supplied by the same person.

MOFO Mass Air Flow Meter

www.modshack.info

MOFO Stand for 'Mass Oxygen Flow Optimiser'. This is a custom made, hand-built Mass Air Flow Meter (MAF) Housing. It consists of only the outer metal housing and all necessary parts to fit the sensor part from the original MAF.

The inner diameter on the MOFO has been increased by 0.15 inch; this has resulted in the inner surface area increasing by more than 11%. An increase in surface area will cause an increase in air volume thus more power. In order to truly benefit from this modification, a full remap is advised.

In order to compensate for the increase in MAF size, I had to replace the original 3bar Fuel Pressure Regulator (FPR) with a 4bar FPR (seen below)

ABD Big Bore Air Intake

www.abdracing.com

"Originally, cars are equipped with an undersized plastic or flexible rubber intake tube. ABD Racing Big Bore Intakes are constructed from an oversized 3" stainless steel tubing that is mandrel bent and then powder coated bright silver to perfection for an increase in air flow into your throttle body. Theoretically, more air equals better performance, and this is the case with the ABD Racing replacement intake system. As mentioned previously, all parts are mandrel bent to ensure a non-disturbed flow of air that cut & welded parts cannot match." ABD Racing

What I noticed:
Initial take-off power reduced due to bigger bore size, but all this means is having to rev the engine more in order to take-off faster. Power gain is small but noticeable and top end speed has benefited also. Main thing I like about this mod is the way it looks.
