GM revised the air filter housing on some 2020 L5P trucks. The A3231C is confirmed for 2017–2019 model years. Check your existing air filter part number — if it's stamped A3231C or 84262965, this fits. If it's a different number, your truck may use the revised housing.

In practice, if you tow, drive gravel, or operate in dusty conditions (construction, agriculture, Southwest desert), replace every 15,000 miles. A $30 filter is cheap insurance against a dusted turbo or scored cylinder walls.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Will this air filter give me more horsepower?\u003c\/strong\u003e\u003cbr\u003e\nA: The A3231C is not a \"performance\" filter in the oiled-cotton sense — it's an OEM-spec replacement engineered for \u003cem\u003ebetter filtration at equal or lower restriction\u003c\/em\u003e. On a dyno, you won't see a horsepower gain. What you \u003cem\u003ewill\u003c\/em\u003e get is cleaner intake air, longer turbo life, and the confidence that your filter media isn't collapsing under high boost. For a true high-flow upgrade on a tuned truck, aftermarket intake systems exist — but for a stock or lightly modified daily driver, this is the filter you want.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Will using an aftermarket air filter void my warranty?\u003c\/strong\u003e\u003cbr\u003e\nA: No. The Magnuson-Moss Warranty Act protects your right to use aftermarket replacement parts. The iFJF A3231C meets or exceeds GM's filtration and airflow specifications. As long as the filter itself doesn't cause a failure (and it won't — it's a direct dimensional and performance equivalent), your warranty is safe.\u003c\/p\u003e\n\n\u003ch3\u003e🛒 Complete Your L5P Maintenance\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeed the fuel filter too?\u003c\/strong\u003e \u003ca href=\"\/products\/tp1015-fuel-filter-and-a3231c-air-filter-for-silverado-gmc-sierra-2017-2019-duramax-6-6l-v8-2500hd-3500hd-diesel-engine\"\u003eTP1015 + A3231C Air Filter Combo\u003c\/a\u003e — $37.99, both filters in one order, one shipping charge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eJust the fuel filter?\u003c\/strong\u003e \u003ca href=\"\/products\/tp1015-fuel-filter-for-chevrolet-cruze-silverado-gm-sierra-2500hd-3500hd\"\u003eTP1015 Fuel Filter\u003c\/a\u003e — $17.99, 5-micron absolute filtration for your CP4.2 pump\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUpgrade your fuel filter cap?\u003c\/strong\u003e \u003ca href=\"\/products\/tp1015-fuel-filter-and-134001-silver-housing-cap-for-duramax-6-6l-2017-2020-silverado-gmc-sierra-2500hd-3500hd-l5p-diesel-engine\"\u003eSilver 134001 Billet Cap + TP1015 Kit\u003c\/a\u003e — $69.99, fix the brittle OEM plastic cap permanently\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp style=\"margin-top:24px;\"\u003e\u003cem\u003e💡 TIP: A dirty air filter doesn't just hurt performance — it increases fuel consumption.

The only thing that will mar it is a slipped wrench — so use a properly sized 32mm socket.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I reuse the billet cap with future filter changes?\u003c\/strong\u003e\u003cbr\u003e\nA: Absolutely.
