61 13 1 378 412 is the angled (90 degree) 3-pin plug housing that connects the wiring to the two-speed radiator fan thermo switch and the auxiliary fan of the BMW E30. BMW has discontinued the part, and dealers now list it as no longer available. Replique labs reverse-engineers the housing from an original and makes new ones in heat-resistant engineering nylon, designed to take the original terminals.
How we reproduce it
- 01
Reverse-engineer
We rebuild geometry from your original - broken samples are fine.
- 02
Design & improve
Weak features get thicker walls, ribs and fillets in CAD.
- 03
Manufacture
Produced in the right process and material for how the part is used.
What to send for a quote
- •Multi-angle photos, including both mating faces
- •Rough dimensions in mm (calipers or ruler)
- •The part number if visible
- •Where it fits on the car
- •Quantity required
- •Deadline, if any
- •Tell us the quantity you need - we will confirm whether the part is viable as a single piece or requires a minimum batch.
Frequently asked questions
Are terminals included?
No - the housing only. You move the terminals across from your old plug.
How do I order?
Request a quote with the quantity you need. We confirm the price and lead time, and workshops can order in batches.
How accurate is the reproduction?
We hold the tolerances that matter for fit and function - mating faces, clip engagement, hole positions - and verify dimensions before shipping.
Which process will you use?
Whichever suits the part: MJF nylon for tough functional plastics, high-detail resin for fine features, CNC for metal or high-load parts, vacuum casting for small series.
Can you produce a single piece, or only series?
It depends on the part, and we are upfront about it. Many components are viable as a single piece and we quote them that way. Others carry engineering, tooling or machine set-up costs that only make sense across a minimum quantity - where that applies we say so at quote stage, with the numbers, so you can decide before committing.
What are typical lead times?
Most plastic reproductions ship within 2-4 weeks of quote approval, depending on complexity and finish.
Will it survive heat near the engine?
We select temperature-rated materials for under-bonnet locations and say clearly what the chosen material tolerates.
Will the colour and finish match my interior?
We match sheen and texture as closely as the process allows, and confirm finish options in the quote.
