There are basically three 'levels' of quality in replacement parts 1/. Genuine or OE (original equipment), as the name suggests the same bit used in the original manufacture and priced and packaged accordingly. Usually best quality and the most expensive option with 'peace of mind purchase'. 2/. OEM (original equipment manufacturer), the same component as manufactured in 1/. by the same suppliers (to eg. Land Rover) but doesn't come in a box with a green oval, ie. same quality without the badge. :) Generally cheaper than OE for the same quality. 3/. After Market, this segment covers all other 'copy' components and can be from the very good or even better than original ie. Superior Engineering products or some absolute cheapy crap from Ali Express that can be built to no standard what so ever and priced accordingly. :(

The much maligned Britpart is a good example of 'after market', they are a company that buys components from various sources and re packages them for the market much the same as Repco does here in Australia. It's a bit like Forrest Gumps box of chocolates, a bit of a lucky dip to see if you've got a good one. :) Sometimes Britpart components are quality OEM product, but often they are not.

From a practical viewpoint, IMO, if you're fixing a car to sell then buy after market, if it's a keeper then buy OEM. If you're nervous about quality and can afford it go genuine. :)

Well had the Defender into the mechanics to determine what is causing the engine fault code to come up. Had the Mechanic ring me up an hour or so after opening telling me it was a faulty MAF and that they have replaced it with a OEM one (Intermode brand) and its good to go. Finally got back there today to pick it up from the smash repairers after getting some corrosion repaired from around the Alpine windows... Started it up and low and behold - there is the engine check light up again... Quick drive back up to the mechanics to complain and they installed their diagnostic tool had another look - the MAF was working... but then it suddenly stopped working. I was told that it might be a possible wiring harness or even a ECU problem.
I said to the mechanic that lets pop the bonnet and I'll wiggle the MAF connection - That's when we noticed the wires going into the MAF Plug looked a bit suspect. Anyway to cut a long story short - the problem all the time was corrosion inside the plug where the pins are joined to the wire. Something that they had seldom seen before. Anyway, once problem was found, they sourced the gear required and rectified the problem - AOK... so far.

Just curious but has anyone else had issues with this MAF plug/connection in regards to corrosion?

I’ve replaced MAF plug with replacement from UK. Reasonably easy splice of new plug onto existing harness. Problem was as you described, corroded wire right where it bends going into plug, terrible design with no strain relief. Anyway, now I have same problem with MAP and it appears the supplier in the UK is no longer supplying due to shortage of components (related to chip shortage I think they meant)
Has anyone been able to find a quality supplier of MAP & MAFs and the plugs that connect to them?
regards
