WHAT STANDS OUT?
Here’s a list of things that stand out with the Straightshot air filter.
(1) Theory. Air filters are one area of motocross development that still has unlimited potential for creative entrepreneurs. There have been fuzzy filters, multi-density filters, paper filters, pleated gauze filters, dual-layer filters, foam-filter covers, nylon-filter covers and green weenie filters.
The Straightshot filter’s two layers of foam are not flame-bonded together. Flame bonding is a process that melts two layers of foam together to allow for easier assembly, but it can reduce airflow. Straightshot uses a petroleum-resistant glue instead.
The one-piece, dimpled design provides a larger surface area than most filters. More surface area allows more air to penetrate the foam. Straightshot uses a very dense foam that still allows for high airflow. With only one glue seam, the potential for seam failure is reduced.
In MXA’s tests, the Straightshot air filter did its job well. We tested it in extreme dust, sand and back in the pack. There were no signs of dirt bypassing the oiled foam. The larger surface area was a plus, making it harder for dirt to get in where the filter is sealed to the airbox. If there was a performance gain because of the increased surface area, it was hard to notice from the saddle, but Straightshot does offer an ultra-thin filter for low-dust tracks that allows for even more airflow and the potential for increased power.
Everything lined up, and there were no hiccups in the installation. We did not have to stretch the foam, and the seal between the cage and the airbox was excellent.
Thanks to its puffy shape, dense foam and single seam, the Straightshot air filter held up to multiple cleanings. We don’t recommend using gas to clean an air filter because of its negative effects on the foam and glue, but we cleaned our Straightshot filter with gas as a test and saw no ill effects.
WHAT’S THE SQUAWK?
No complaints, except for spoiled test riders who prefer their filters pre-oiled out of the bag.
A good, solid air filter with a couple of smart ideas that set it apart from the crowd.
