Quick Overview

Improve your Porsche Boxster's gas mileage and performance by replacing your worn out air filter with a higher quality aFe Drop-in Air Filter.

Sku # : aFe-Drop-in-Air-Filter-Porsche-Boxster-CM
Your Porsche Boxster needs a lot of air to be fed into the engine to reach its potential performance level. The OEM air filter is very restrictive and clogs easily. For the best performance for the money, upgrade your OEM air filter to the aFe Drop-in Air Filter today. The aFe Drop-in Air Filter uses mesh cotton gauze filter elements to effectively trap debris while allowing maximum airflow to your engine. The results are increases in power and improved throttle response. Since the Porsche Boxster engine will be able to breathe easier, you will also see improved gas mileage while driving. aFe Drop-in Air Filters can be washed and reused, eliminating the need to buy replacement air filters ever again. Since the aFe Drop-in Air Filter for the Porsche Boxster is a direct OEM replacement, installation will only take you about 15 minutes.
aFe offers their Drop-in Filters in 2 types: their oiled Pro 5R filter and their oil-free Pro Dry S filter.
