QUESTIONS & ANSWERS
Q: reusable versus replacement? WigB 3 years agoAnswer
Do you recommend a reusable air filter or one you have to replace? Is one better for performance? Do you really get that much improvement in airflow with these aftermarket filters? Thanks.
A: Single use filters are not necessarily any better or worse than reusable filters, but reusable filters are generally a better value because you can clean them rather than spending money on a new one. Performance depends more on the design than single or multi use, and one is not overall better than the other. Aftermarket air filters do increase airflow and usually by about 15-30% over stock.
