Our air filter kits are used on any Bosch 74mm or 82mm electronic or DBW throttle body.
Precision machined from aluminium, bead blasted and clear anodised, these simple and elegant adapters provide smooth airflow and use an O ring seal to the throttle body and includes fasteners, O ring, air filter and K&N air filter adapter.
Featuring two options of K&N air filters depending on your power requirements.
- Small Filter is good for fast road cars, 3.6L and under
- Large Filter is good for up to 4.5L, 8,000 Rpm engines, 1.8x filter area of the smaller filter.
Both filters are the similar effective height.
We generally recommend the small filter for our 3.2 and 964 E-throttle kits, and the large filter for the GT3 E-throttle kits.
We also offer the adapter as its own kit. This is used for any application where a Bosch 74mm or 82mm throttle or for our 964 E-throttle applications where the factory intake boot is desired to be used. This adapter works perfectly with our E throttle kit and the factory air flow meter and air filter.
