Howdy,
Anyone replaced OE secondary air injector pump or check valves with aftermarket? Can't afford 3-4 times the price for OE right now but don't wanna cause more issues down the road.
2015 Tacoma is in limp mode. Codes: P0418, P2440, P2442.

Fuses, relays, wiring are fine. No cracks in hoses. Pump had a tiny bit of water inside. Foam filter inside was actually fine.

Anyone have good experiences with aftermarket off Amazon in these parts or I'm taking a huge risk?
