A Snake,
You are correct about running with no air filter except I live in a very dusty area and would have a motor full of sludge in about 100 miles. But I have ran mine for short drives when working on it with the filter off and noticed a seat of the pants increase. I did go to the K&N Filter and that made a huge difference over the filter I was using. I do change my
oil very often and after any hard, long run. Some people around here think I am crazy to use so much
oil but I feel
oil is cheaper than motors. And I do my tuning with the filter on and everything just like I drive it.
