I just thought I would add something here to make you guys aware of what an exposed air filter gets..
I recently purchased a little temperature display with temp probe.
I will be using this to see what the air temp is just before the throttle but haven't drilled a whole just yet.
In the meantime, I have stuck the probe in to one of the groves on the K&N Pod filter.
just as a test here are some results..
driving in traffic the other night, the ambient temp displayed that it was 22 degrees outside.
the temp probe showed 54 degrees at the pod filter.
when I got to on Gladesville bridge, i travelled at about 80km all the way up towards lane cove.
the ambient temp showed 21 and the pod filter showed 32.
once I slowed back down to 60, the pod temp went up to 40.
I will be boxing this up asap and will post some more results for those interested as to how much of a difference it makes.
I don't have the original air box so I can't test that..
The probe is very acurate too.
it is within 1 degree of acuracy, anywhere between negative 50 to positive 150 degrees.
Don't know about you guys, but these temps are now with the cooler wintery temps.. can you imagine what my engine was breathing in during those few high 30's days we had in summer?
