An impressive 74HP with 90LBFT gain can be seen from this must-have package! Our Road and Track proven ECU software calibration takes the Mx35i to another level boasting up to 400HP
This package is designed for those seeking an improved soundtrack to their engine while picking up some extra horsepower also, Turbo spool and low-end response will be dramatically improved from the free-flowing downpipe. For those wanting to retain road legal (MOT) status, we advise a sports catalyst is required, otherwise, for optimal gains, a decatted downpipe is installed.
As standard for the downpipe, we offer the Wanger catted or catless optionals. We can also supply Milltek, Scorpion and Remus downpipes also
With this tuning package, there are a few options;
– The first one we offer is to install uprated charge pipe(s) as the standard cold side charge pipe is common for breaking under increased boost levels. For reliability reasons we highly recommend this upgrade.
– High flow air filter drops in place of the standard paper filter into the standard airbox, this is a high-quality high flow, synthetic nanofiber filtration media which is pleated to maximise surface area and in turn increase airflow, freeing up a few extra horsepowers. Or full Induction kits can be offered.
– Cat-back systems (creating a turbo back) will allow maximum exhaust flow breathing capabilities while improving the exhaust note even greater, with a few options to suit all tastes and budgets, Check Exhaust filter
– A highly recommended complimentary upgrade for the Automatic 8 Speed ZF gearboxes also includes a Gearbox tune (TCU) from xHP Read here for more information.
