ITB air filters

[siverson]

What are the various options for air cleaners on an ITB (Individual Throttle Body) equipped car?

Plus, are they required? Probably, but they look -so- nice without them! Note the three photos below.

1. Full air cleaner
2. "Mesh" covers
3. None

Any info?

What's an "ITB equipment car"?

As far as air filtration, the three cars exhibit these characteristics

black car: ITG foam filters. Air is filtered
orange car: Screen. Leaves, large pebbles are filtered; better than nothing
yellow car: No air filtration. Set up for show.

If it's a question of what type to use, something along the lines of the factory or ITG filter is suggested (even K&N). There is hardly any additional power gain from removing the air filter and plenty of potential drawbacks. They mostly center around ingesting non-compressible objects into the engine for immediate "wear" and gradual, but accelerated wear in long-term use.

I think Steve means "Individual Throttle Body"-equipped, Sherwood.

Some other alternatives for filters discussed in this thread.

Tom,
Okay ITB = individual throttle body

But the yellow car looks like it has Webers.

Steve, can you elaborate?
