Quotes Hi. Used the filters at the vintage race associated with the Houston Indycar race. They fit perfectly and did not reduce power on the dyno. The Suzuki o Quotes

Quotes Hi, When we did the Dyno tuning on my car we tried one run without the air cleaners and immediately following a run with the air filters, the result was only a difference of 2 HP less, which could have been Dyno error reading of just difference in engine run. Based on this, I would say that your air cleaner screens do not have any negative effort on engine performance. Tom Quotes
