EMP Oil Filter 35-57801, Replaces 18-7824-2 / 35-866340K01, Fits 454-502 CID V8 Marine Engines

The EMP 35-57801 is a spin-on oil filter built as a direct replacement for OEM oil filter 18-7824-2, cross-referencing to 35-866340K01. It is designed for use in V8 marine engines ranging from 454 CID (7.4L) up through 496 CID (8.1L) and 502 CID (8.2L), covering a wide span of model years from 1978 through current production. The filter installs in place of the original equipment part using the same mounting and threading, making it a straightforward swap during routine oil changes or engine maintenance.

This filter is intended for use with 25W-40 FC-W marine oil across most covered engines, and with 20W-40 synthetic catalyst-rated oil on catalyzed 496 Mag. And 496 Mag. HO applications. It weighs 1 pound and carries UPC 840080472393. Because the correct oil filter and recommended oil type vary by specific engine model and year, confirm your engine model against the fitment list before ordering to ensure you select the right filter for your application.

Frequently Asked Questions

What does the EMP 35-57801 oil filter replace? The EMP 35-57801 is a direct replacement for OEM oil filter 18-7824-2, and it cross-references to 35-866340K01.

Which engines does this oil filter fit? This filter fits V8 marine engines from 454 CID (7.4L) through 496 CID (8.1L) and 502 CID (8.2L), including models such as 400 TRS, 420, 425, 454 Mag. (including Alpha, EFI, and MPI variants), 465, and 496 Mag. (including HO and Catalyzed versions).

Is the EMP 35-57801 the same as OEM part 18-7824-2? Yes, EMP 35-57801 is built to replace OEM oil filter 18-7824-2, so it functions as an equivalent for engines that call for that filter number.

What years does the 35-57801 filter cover? Coverage spans engine model years from 1978 (400 TRS) through current production (496 Mag. And 496 Mag. HO Catalyzed models beginning in 2011), depending on which specific engine model you have.

How much does this oil filter weigh? The EMP 35-57801 oil filter weighs 1 pound.

What oil should I use with the 35-57801 filter? Most covered engines call for 25W-40 FC-W marine oil, while catalyzed 496 Mag. And 496 Mag. HO engines require 20W-40 Synthetic Catalyst-rated oil.

Does the recommended crankcase oil capacity change by engine model? Yes, crankcase capacity varies by engine model when using the 35-57801 filter, ranging from 5.7L / 6.0 Qt. On the 420 model up to 8.5L / 9.0 Qt. On the 496 Mag. Models, so check your specific engine model before an oil change.

Will the 35-57801 filter fit a 454 Mag. Alpha engine? Yes, the 454 Mag. Alpha V8 (454 CID / 7.4L, 1986 - 1988) is one of the engines covered by the EMP 35-57801 oil filter, which replaces OEM 18-7824-2 on that application.

What is the UPC for this product? The EMP 35-57801 oil filter carries UPC 840080472393.

Can I use the 35-57801 filter on a 496 Mag. HO Catalyzed engine? Yes, the 496 Mag. HO (Catalyzed) V8, 496 CID / 8.1L, 2011 - Current is covered by this filter, and that application should use 20W-40 Synthetic Catalyst oil rather than 25W-40 FC-W.

What part number should I search for to find a compatible filter? Search using 18-7824-2 or 35-866340K01, both of which the EMP 35-57801 oil filter replaces or cross-references.
