Here we profile one of the more important aspects of turbo
performance. Air intake systems. A high flow intake will
increase boost response significantly. In most cases peak boost
rises from .5 to 1 psi with no other modifications. Additionally, it
allows the turbo to breathe at the top end of the horsepower curve where
the stock filter runs out of air. Surprisingly however, the stock
filter does a nice job of moving air. Rather than the typical paper
filter most cars use, it uses a dense cotton type material. The problem is that they clog very easily,
and cannot be cleaned. Included below are part numbers and
retail pricing.

These are aftermarket performance filters that are not necessarily
designed to be on a Celica All Trac. The companies offer universal
versions that can be adapted with minor modification. In most cases
this requires removing the battery and relocating it to the rear.
You can read about an All Trac Club member that performed this
modification on his ST185 All Trac. Some filters require a universal
adapter which turns the 3sgte Air Flow Meter into a 3" round opening which
most filters accommodate. More information about this adapter is
found at the bottom of the page. |

release key at the front to remove screen and foam without effort. |
