Automotive enthusiasts, this is the silver bullet! Based on my observations, the AUTOHAUX Cleaner Spacer Filter worked wonders on my engine by clearing up the air flow. My car felt more responsive with a little extra power added to the acceleration .The installation was quick and easy with no hassle. The only downside is that it's a bit on the pricier side for a filter, but it's worth the investment for a performance enhancing product..
