Air filter myths/don't dos

  • Never leave the filters in the sunlight to completely dry as UV will at some point ruin the foam (obtains hard and splits).
  • Do not oil filters that are not completely dry due to the fact that it can create hydrolysis which can break down the foam.
  • Spray-on filter oil is alright but generally less thorough for enduro and off-road occasions where challenging conditions for the filter (dust or water) is a bigger factor.
  • BIO oils are alright yet more at risk to breaking down as well as allowing water to pass the filter in wet conditions.
  • The more "porous" the air filter, the more power you'll obtain. This is a reality but the gains in BHP you might see or find out about with some filters can be just as diverse as a result of how the power on a dyno was determined as well as consistency with testing. Do not trust every little thing you review.
  • Covers and also skins are preferred in messy conditions or sand races however they restrict airflow and power. The more layers of foam (or dirt), the much more restrictions there are to air circulation.
  • A well-maintained air filter effectively oiled will do its work as well as in the worst of conditions it is far better to change the dirty filter with a fresh one than fit a cover.
