EPAuto GP309 Engine Air Filter (FRAM CA4309) — DIY Swap in 10 Minutes! $33.82 CAD (37% Off)

Amazon.ca has the EPAuto GP309 engine air filter (FRAM CA4309 cross-reference) for $33.82 CAD, down from a $53.94 list price — 37% off. Prime members ship free; otherwise free over $35.

An air filter is the easiest maintenance item to forget. Once it loads up with dust, the engine breathes harder, throttle response feels flat and fuel economy drifts. EPAuto recommends replacing it every 12,000 miles — worth doing sooner if you drive through a pollen-and-grit spring.

Fitment covers a long list of cars: Nissan Altima (L4 1993-2006 / V6 2002-2018), Maxima (1981-2021), Murano, Pathfinder, Frontier V6, Sentra, Xterra V6; Infiniti G35 (VQ35DE only), FX35, QX60 V6, I30/I35; Subaru Forester Turbo (2004-2008), Impreza (1993-2007, excluding California emissions), Legacy (1990-2004). Check your year and engine in My Garage first — one owner found it wouldn't fit a 2004 Legacy, which uses a ~14" filter versus this 11" one, though the return was painless.

Installation is a few clips, pull the old filter, drop the new one in the same orientation. Ten minutes in the driveway — and at a shop, the labour on a job like this usually costs more than the part.

4.6 stars across 411 reviews, ranked 8,216 in replacement air filters. This category almost never goes on sale, so 37% off is unusual.
