3.3.2.4 Temperature Rise
The intake of air must avoid the suction of air coming from the hot spot areas of the inside of
the engine bay such as proximity to exhaust manifold.
As referenced in table 3.3.2.4 - I, development power and torque data is shown to illustrate
the order of magnitude that may result as increasing the induction temperature.
3.3.2.4 Filtration Requirements
GMPT requires an air filtration medium that is capable of removing 98.7% of the material
contained in reference material SAE “Course Dust”.
The following table shows the different Air Cleaner ASM and Components coupled to the
L35 engine per GM platforms.
