Quick answer

Run the -6AN kit if your feed line and fittings are already -6AN and you want a compact 70mm in-line filter with a stainless 100 micron element. Choose the 10AN female kit when your plumbing is -10AN and you need the larger connection size to match the rest of the system.

Connection size is the decision, not the micron rating

Both DeatschWerks kits use a stainless steel 100 micron element in a 70mm housing, so filtration rating is not the differentiator here. The real split is the connection: the -6AN kit uses -6AN fittings, while the 10AN kit uses 10AN female connections. Match the kit to the hose end and adapter you already have rather than adapting down later.

A 100 micron element is a coarse pre-filter grade, so it suits protecting pumps and catching larger debris. If you need finer filtration downstream, that is a separate filter choice, not a reason to pick one of these kits over the other.

Where each kit fits without extra adapters

The -6AN kit is the simpler drop-in for a -6AN feed line: the fittings are already the right size, and the 70mm housing keeps the filter compact in tight engine bays. The 10AN female kit is the direct fit for -10AN plumbing, where forcing a -6AN filter into the line would mean reducing adapters on both sides.

Neither kit lists a pressure rating, flow figure or replaceable element specification in the supplied catalog data. Treat those as open questions to confirm before you buy if your build depends on them.

Trade-offs at a glance

  • -6AN kit: compact and simple: Best when your feed line is already -6AN. You get the 70mm housing and 100 micron stainless element with no adapters, but the smaller connection limits how it matches larger -10AN plumbing. Check your hose end size before ordering; a -6AN kit on a -10AN line means reducers.
  • 10AN female kit: matches larger plumbing: Best when your system is built around -10AN lines. The 10AN female connections avoid step-downs, but the larger fitting size takes more space and may not suit tight routing. Confirm you have 10AN male hose ends to mate with the female connections.
  • Same filtration, different plumbing: Both kits share the 100 micron stainless element and 70mm housing size, so pick on connection size and packaging space, not on filtration performance. If you need a finer micron rating, this pair is not the deciding factor.

Product facts

Which kit fits your build

Best for

  • Builds with an existing -6AN feed line that want a compact 70mm in-line filter
  • Systems plumbed in -10AN that need female connections without reducers

Not for

  • Anyone who needs a documented pressure rating or flow figure, since neither kit lists one
  • Builds that need a finer micron rating than 100 micron
