❓ FAQ
Replace the TP1015 element every 15,000 to 22,500 miles (24,000 to 36,000 km) and drain the water from the filter housing at every oil change. In dusty or high-water fuel conditions, replace sooner, since the 5 micron absolute media loads faster than a nominal element.
No. The A3231C air filter is a drop-in for the 2017-2019 Silverado and Sierra 2500HD / 3500HD air box only. The kit is listed for 2017-2019 plus the 2021-2025 Silverado 4500HD / 5500HD / 6500HD, which use the same A3231C panel; it does not cover the 2020 and later L5P pickup air box.
Absolute at 5 micron means beta 1000: 99.9% of particles at that size are captured, not the 50% a nominal rating implies. The 98% water separation refers to free water knocked out by the hydrophobic barrier, which collects in the housing instead of reaching the high-pressure pump.
No special tools. The TP1015 cartridge lifts out once the housing cap is removed, and both Viton O-rings are included. The A3231C panel clips into the factory air box after the lid is unclipped. A socket set for the housing cap and a drain pan are enough.
One TP1015 fuel filter cartridge, two Viton O-rings, and one A3231C panel air filter. All carry a 90-day warranty against manufacturing defects; the warranty covers the parts themselves and does not extend to labour or consequential damage.

Description
Product Overview
The FJ-AF07-TP1015 kit covers both filters in one service on the 2017-2019 Chevrolet Silverado and GMC Sierra 2500HD / 3500HD with the 6.6L Duramax L5P turbo diesel: the TP1015 fuel filter cartridge that drops into the factory housing and the A3231C panel engine air filter.
The TP1015 element is rated 5 micron absolute with 98% water separation and ships with two Viton O-rings for the housing. The A3231C air filter uses a foam pre-filter layer over pleated paper and drops straight into the original air box. Together they cover the fuel and intake side of one maintenance interval.
