Sprint Filter P037 Air Filter Honda CBR 1000 RR SC77 (2017-2019) PM158S-WP

When the track demands maximum protection without surrendering a single horsepower, the Sprint Filter P037 PM158S-WP is the race-bred answer for Honda CBR 1000 RR SC77 owners. Proven at the Bonneville Salt Flats during world speed record attempts and trusted by teams competing in the Bahrain Superbike Championship, this waterproof polyester filter filters particles down to 37 microns while delivering airflow equivalent to the celebrated P08 — no compromise, no excuses.

Key Features

• Ultra-fine 37-micron filtration captures dirt, dust and debris without choking the engine, keeping internals safe under the harshest racing and road conditions.
• Fully waterproof construction handles standing water, rain and muddy circuits where a standard cotton gauze filter would be compromised.
• Airflow performance matches the P08 performance filter, so there is no power sacrifice in exchange for increased protection.
• Near-maintenance-free servicing — a blast of compressed air is all that is needed; no oiling, no specialist cleaning kits, no lengthy drying times.
• Durable polyester medium retains its structure and filtration characteristics through years of extreme use, far outlasting paper OEM elements.
• Backed by over 65 years of Sprint Filter manufacturing heritage and race wins across MotoGP, Moto3 and the World Superbike Championship.

Track-Proven Performance

The P037 designation refers to Sprint Filter's tightest-weave polyester specification, engineered specifically for environments where conventional filters fail. On the Bonneville Salt Flats, where fine salt crystals and alkaline dust are ingested at triple-digit speeds, the P037 helped riders set multiple land speed world records. In the Bahrain Superbike Championship, where desert dust and extreme heat are a constant threat, teams chose this filter for its ability to protect engines race after race. For CBR 1000 RR SC77 owners who push hard on track days, enduros or simply ride in wet British conditions, that same race-validated filtration is now a direct, drop-in upgrade.

Build Quality & Materials

Sprint Filter constructs the P037 from a proprietary polyester medium that is inherently waterproof rather than treated with a coating that can degrade over time. The medium is precision-woven to the 37-micron specification and bonded to a rigid frame that sits flush in the Honda OEM airbox, requiring no modification. Because polyester does not absorb water or oil, the filter's flow characteristics remain consistent whether the filter is dry, damp or freshly cleaned — a critical advantage when racing or riding in variable conditions.

Fitment & Compatibility

The Sprint Filter PM158S-WP is a direct OEM replacement for the following motorcycle:

• Honda CBR 1000 RR SC77 — model years 2017, 2018 and 2019

No airbox modification is required. Fitting follows the same procedure as replacing the standard paper element.
