Aftermarket 90s era TFI. Even says “made in USA” on it. No idea who made it but we can compare to the previous pics

Edit: looks like the Filco F0311

Here’s a picture of the new Delphi that gave me a slight miss-fire on occasion.
That’s disappointing a Delphi part would give you a problem. They have been a premium electrical manufacturer started by GM. I wonder if they made it or if they reboxed the part.

In about 92-93, (1993, not 1893), we received two shipments of genuine AC Delco 4 terminal HEI modules almost straight from the plant in Mexico. They were all bad. After putting two on my Olds, I took a tester to the the rest and warranted them all. At that time, the Accel part was a better choice.

I agree. I've always though highly of Delphi products.

Yea that's the same cover that I took off the filko.... Just to show how really :poo:ty the aftermarket is now I ordered a new tfi and pip from AutoZone since they claim to be wells and a motorcraft pip is a pita to find these days.. wells is now WVE. The tfi is the same as the one I posted, came in a duralast box with wells paperwork. Now here's the best part. The pip/ stator comes in a duralast box, no paper work, inside a generic white box with 6187 part number from china. Which is forecast/OEM, aka Standards cheapest line kind of like there T series stuff..... The best part, it was drop shipped from standard motor products in Va. Every one is just reboxing :poo: these days.

Same here. This is not good to hear. Hopefully their fuel pumps are having better luck as I just put two of them in my current truck project. Well, good thing there's a lifetime warranty on them. I had a pair of Walbro pumps on order and cancelled after a couple months of waiting.

Since the pics are dissecting parts, figured this would fit in here. I found a sealed "dead stock" (aka closed auto store) reman. Mass air auto eec IV It was less then a core so i snagged it since prices are down right stupid these days. its BSEs part number for 88-93 auto. They removed the oem sticker and cal catch code but the board tells me its an A9p or equivalent. No idea when it was rebuild as its not dated.


I wanted to check the caps before installing it and see what they repaired so I broke the no "warranty" seal and glad I did. The one closest to the j port is shot, that one typically keeps the fuel pump on when keyed off. Surprisingly there factory caps so I'm not shocked that it leaked after 30 plus years. I gave the board a once over, no burnt traces any where instead it looks like they swap the chips onto good core boards, which explains why they relable them, if you look close will see the white pin connector is scribed e9zf-ca but this is covered by the case so you can't see it without removing it. Time to order another batch of capacitors and get this one back in order as a spare.

For anyone who wants to compare the current buy "motorcraft" tfi..... here's the budget standard lx218T, T series line a lot of parts stores carry but fail to disclose its the cheaper t series line,..... Same boad, same components, 1 less connection on each pad, sadly I don't have a current lx218 none t series to take a part to confirm it has 2 connections on each pad like the motorcraft. Last 2 I order online came in t series boxes and can't find it local.

local advanced has drive works I have no clue who makes it but case mold isn't same as standards , Napa echlin TP31 Is a rebranded standard but at more then a motorcraft im not checking if its a t series or not lol. AutoZone has the motorcraft the cheapest or the duralast from wells, no one local sells the normal lx218, same goes for there ignition pick ups and coils, they are all the t series or even worse forecast oem line here, been trying to find an older blue streak coil and lx222 pick up. quality Ignition parts are getting harder to find, sad when even the perfomance aftermarket is selling you low quality parts store replacement stuff at stupid mark ups, but hey that Holley these days since they own msd and accel..

I found some tfi's on eBay for less then $ 9 shipped from a parts liquidation company that wasnt a china drop shipper so ordered 2, I was shipped 2 loose but packed well in a padded envelope both wrapped in a decent amount bubble wrap. They where old stock and had bwd "select" series stickers on them, one was a 218 other was a lighter grey 223 but SMP has consolidated those part numbers these days making auto/manual the same. The Select series where the top line, much like standard they had 3 and are the same parts just bwd branded, z series, p series and select. the select has double connections like the motorcraft, I killed the cover taking this one apart lol.

Order another pair, not sure if they will all be the same but for less then the retail price of one I stocked up. Guy sold around 50 and has a few left, all the parts store ignition parts seem to be getting consolidated into the cheaper lines at least at my local stores Also Grabbed a few standard blue streak made in Poland coils, from other retailers, you can get them in black now with blue streak branding vs the old blue ones.

Standard seems to have also consolidated the lx222 pick up into a single molding now. the moldings for the more expensive old blue lx222's was a bit different from the du30 motorcraft, the motorcraft is impossible to find so that's a crap shoot now that there all black and even the lowest quality ones look the same.

So...basically...if you take a cheaper one apart and solder another wire on each pin then it would be the same is the later Motorcraft ? Maybe I missed something.

Pretty much, its the same part with way less quality leads on the t series stuff but your not going to have much luck soldering them with the film they use on the boards.. The lx218 you can buy from a few parts stores still with a lifetime warranty like oreillys, just not in my state..... its the same exact part as the motorcraft dy1284 that only has a 2 year warranty.. Funny AutoZone just doubled there price for the motorcraft part lol. The T series stuff is designed to fail out of warranty, look at melted lead in the pic I posted... Weak coils and pickups kill these more often from voltage issues then residual heat from the distributor.
