It’s ironic that as the initial Jaguar story neared publication, I ordered an aftermarket part to complete the (somewhat) light restoration of my 1988 Mercury Cougar XR-7. I mentioned getting “a factory part when buying the aftermarket brand” and nobody had a problem with this assessment.

But you won’t believe what happens next in this shameful attempt at clickbait

The most readily available and cheapest part was from AutoZone under their Duralast house brand. No surprise there, I guess.

But what came out of the box was a pleasant surprise: the more expensive Ford part with a legit FoMoCo part number! Choosing aftermarket on my Cougar isn’t living dangerously, as a Ford Fox chassis is a far less fussy feline than a Jaguar S-Type. But still, it proves my point about the “quality” of aftermarket parts.

Every time I depress the clutch and twist the ignition, I will remember the factory switch that came from a low-brow box.

    Aftermarket parts can be like some German sourced BMW parts, the same but a dremel tool cut off the BMW logo. I got some discs from Centric and pads for one car...exact as the OE part coming off...not close, the same part.... Bosch makes replacement parts for everything, but the quality can vary. I've also been bit with shock mounts from China in one car-rubber bits aren't just black and rubber-folks make whole careers about rubber hysteresis . I always try for, if you can get the info, the OE supplier, and if not, suck it up and OE. I hate though how that OE part, without the BMW logo dremeled off, in a fancy white box, is twice the price, though

    Back when I owned my 87 T-Bird 3.8 I figured the ignition module that is mounted on the side of the distributor would eventually be an issue due to excessive heat. I knew other Ford owners who had to replace them. So I ordered one from JC Whitney as a spare. It was in a box that looked like a Motorcraft package but without the lettering and was made in S. Korea. The part looked like the original but without the Motorcraft and Ford logos moulded into the plastic case. When the original unit went bad at around 100k I replaced it only lasted for a bit over a year. Then I replaced it with a genuine Ford Motorcraft part which lasted several years until I sold the car at 187k due to a bad head gasket. With my 95 MN-12 4.6 I only use genuine Ford or Motorcraft parts even the battery which is actually a better deal from the dealer that your local auto parts store. They usually have specials. Though recently I replaced the belt tensioner with a new and improved part from Dayton made of course in Dayton, Ohio.

  • MaintenanceCosts Imagine that... the OEM that doesn't make absurd false claims about "Full Self-Driving" and that doesn't release beta software onto public streets gets better treatment from the regulator.
  • MaintenanceCosts Yes, yes, balance, quick turn-in, working the gears, blah, blah.I'm sorry, none of it is convincing. A 3-series needs two more cylinders than this so that it doesn't sound like a Jetta on $199/month special.
