Sprint Filter P08 Air Filter for Road & Track – QJ Motor SRT 600 SX (2024–2026) PM209S

Sprint Filter cuts two everyday cloths for this housing, and they are not ranked one above the other. The P08 on this page works at 80 microns and passes a rated 5,050 l/m²/sec; the P14 filters to 14 microns and passes 1,800. The finer weave holds back more and lets less through, and that exchange is fixed — no medium escapes it, and neither is the better filter in the abstract. For an SRT 600 SX the answer is decided by the surface under the wheels, not by which figure looks more impressive on a specification line.

Key Features

• P08 specification: dry woven polyester, 80 µm, 5,050 l/m²/sec
• The same airbox also accepts the P14 at 14 µm and 1,800 l/m²/sec for dusty work
• Goes straight into the series housing — nothing modified, no remap afterwards
• Retention measured at 93.13 % of 100-micron particles
• Approximately twice the filtering area of an ordinary performance element
• Dry from manufacture, washable, and warranted for two years

Deciding by conditions

The two cloths sit within about a tenth of each other in price, which is small enough that cost has no useful vote in the decision. Conditions do. Sealed roads, mixed weather and the occasional circuit day are the case the P08 was drawn for, and it is the medium Sprint Filter designates for road and track use. Unsurfaced roads, harvest dust, long stretches of loose surface: that is where the P14 earns its lower flow figure, and where accepting less throughput in exchange for finer retention is the sensible trade rather than a downgrade. Owners who ride both ways sometimes keep one of each and swap by season, which a washable element makes practical.

What neither cloth can do

Whichever way that choice falls, it is worth stating the boundary. Neither medium makes a standard SRT 600 SX noticeably stronger. A production engine is fed by an airbox, a set of throttle bodies and a map that were signed off together, and an element sitting inside that system does not rewrite it. The gain is elsewhere and smaller: an intake restriction that begins low, and a part that returns to its own starting point every time it is cleaned instead of drifting further from it until someone buys a new one.

Care and cleaning

Air first, water only when air is not enough. Play a compressed-air line across the clean face so that trapped dirt leaves the way it arrived, rather than being pushed further into the weave. For an oily film, lukewarm water with a small amount of mild detergent will shift it, followed by a full rinse. Dry it in moving air at its own pace, well away from heat guns, radiators and flame, and fit it back dry and untreated. The PM209S maintenance sheet is in the Downloads tab on this page.
