Sprint P08WP Waterproof Air Filter for Harley Davidson XL883 XL1200 XL50

Sprint Filter P08WP - The Waterproof Polyester Air Filter
Replaces OEM Part No. 29331-96

The Sprint Filter P08WP polyester air filter is the culmination of more than 60 years of research, development, and experience at the highest levels of competition.

P08WP is a unique, ultra-fine tissue that offers all the advantages of Sprint Filter's P08 tissue but with the added benefit of being waterproof. The technology used is the same, but with the addition of a special treatment formulated by Sprint Filter.

P08WP has been tested according to the ISO 801 standard (determination of resistance to water penetration -- hydrostatic pressure test), and the Wilhelmy plate method for determining the contact angle between a liquid and a surface. To call a filtering element water-repellent, the contact angle must be greater than 90 deg, otherwise the liquid would pass through it's mesh.

The result is a uniquely waterproof air filter suitable for use in all weathers, without the need for a cover or sock.

More Power and Better Filtration

Cotton and foam air filters typically boast that they deliver more power than OEM filters through improved airflow. Which is often true; the performance of many bikes can be improved with increased air flow using cotton and foam filters. The problem is however that the improved airflow usually comes at the expense of filtration performance. And poor filtration is not good for engine longevity.

The deep-fold design of Sprint Filter air filters, combined with the ultra-fine but highly permeable P08WP polyester material, results not only in increased air-flow but also in superior filtration performance. 

In indepedent lab testing, P80WP produced greater air flow than any other leading brand filter (with the exception of one cotton gauze 'race' filter and Sprint Filter's own P08 filter).

P08: Filtration: 80 microns - Airflow: 5.050 lit/m2/s
P08WP: Filtration: 37 microns - Airflow: 4.750 lit/m2/s

So where a higher flow air filter will improve your bike's performance, P08WP will take advantage while also providing improved filtration, contributing to the longevity of your engine.

Improved Fuel Economy

P08WP's precision-manufactured, ultra-fine polyester filter element provides air flow that is more consistent than typical after-market cotton and foam filters. Air flow consistency helps the bike's ECU maintain the optimum air/fuel mix, resulting in improved fuel economy.

Virtually Maintenance Free

To clean your Sprint Filter P08WP, simply remove the filter from the airbox, blow it clean with compressed air, and re-insert it. No messy washing, after-market cleaners or oil treatments required, saving you valuable time and money!

Long Lifecycle

Being man-made, the P08WP's polyester material will, if properly looked after, display no discernible deterioration or loss of structure or performance over the lifetime of your bike.

Bulid Quality

With 60 years of experience in producing air filters, and success at the highest levels of competition (including MotoGP, Moto3 and World SBK), you can be confident in the quality of materials and manufacture of your Sprint Filter P08WP air filter
