You are correct in that transaction charges are vatable. Not an issue if you are VAT registered (as we are) but another hit if you’re not.

We never took Amex (even in the days of slide-over card impression machines) as the fees were exorbitant.

Is the primary resistance quoted?
A link to the actual item would help.

This ^ and is it a known brand? Advice in general: If no brand and made in China, abstain from ordering.

If it's properly "farked" .... cheap socket, tap it on, weld it to it, then it'll come undone.

They don't get stuck on their threads, just compressed the seal o-ring and if done too tight by previous O then "splaying" the filter housing.

The bolt diameter is quite big as it houses the oil pressure bypass valve to accommodate if the paper filter gets blocked as emergency through route.

The flange is relatively small in it's overhang from that bolt diameter, but probably difficult to cut off without risking the housing.

A really good new/sharp set of "cobra" waterpump type pliers can get onto the outside of flange to succeed sometimes .... keep your fingers out the way though    in case they slip.

It's an odd one, because they aren't usually stuck that much, as in not seized solid, just enough to prevent easily coming undone with a mangled hex.

All because people avoid warning not to tighten them too much.

I measured the primary resistance at 4.7 ohms.
I can’t work out how to share the actual link but copy and paste this into eBay and you’ll get it.
