I just purchased a Seiken, new part, not reman, has a stamp identical to the original OEM part, and the rest of it looks identical as well. The sticker on the top does say Bosch. I'm thinking Bosch is an/the OEM supplier. I realize @Onur doesn't agree, but even his story about finding multiple Bosch units on Toyota shelves supports this theory. How many douchnozzles are buying Bosch units to perpetrate this fraud? Why not something else? There are much cheaper options that would do the trick with a coat of gloss black. Or maybe I'm wrong. I choose to believe I beat the system and got an OEM part for half the OEM price.I just replaced my brake booster with the Toyota OEM part. It was identical to the 25 year old part that came out. JCK ? Was the manufacturer for both the original and the replacement. Either way the brakes are back to perfect and I can stop again.
Your Seiken in the picture is the exact same part as the Toyota OEM that I put in yesterday. So perhaps Seiken and JKC are the same manufacturers?

My obviously aftermarket reman booster in my other truck has the same stamp, but it would if it's a reman, wouldn't it? No paint and an odd sticker on top leaves no question as to its heritage.

On that part I agree with @Onur that Seiken (a self-proclaimed chemical manufacturer) probably doesn't manufacture them. I think they just box them, but that's a guess. There's no good reason for Seiken to print 'BOSCH' on the label if Seiken is making the part, unless one is a subsidiary of the other, which I doubt. In any case, referring to my original OEM part, if we go with Aisin/Advics being the manufacturer it would be the first of their parts that I've ever seen that doesn't have their name stamped, embossed, or printed on it.Your Seiken in the picture is the exact same part as the Toyota OEM that I put in yesterday.

Either way I'm confident that the part being sold by @Onur is in fact the Toyota genuine OEM partOn that part I agree with @Onur that Seiken (a self-proclaimed chemical manufacturer) probably doesn't manufacture them.

I have no idea what JKC is, maybe a factory, country, or licencing mark. Or a manufacturer.

Absolutely, and if you have so much money that blindly paying double for the same part is acceptable, then I envy you.Either way I'm confident that the part being sold by @Onur is in fact the Toyota genuine OEM part

No, it's in reference to the person quoted. If he must have a Toyota box with his part, then by all means you are a great source for a part from Toyota, and an excellent resource to the Toyota community in general. I personally can't afford to pay for the box when the part in a different box is half the price, and we're talking about hundreds of dollars. I usually don't quibble over less expensive parts that come with a premium price in a Toyota bag or box. I am a believer that a person cannot go wrong using genuine Toyota parts, and they are almost universally superior to aftermarket copies. That being said, if I can find the same exact otherwise expensive part for less, I'm all over it.Is this in reference to me?

I understand there is a douche nozzle on here that loves to complain about my pricing. I could care less what he thinks.
LOL, beat me to it.totally understandable and no one faults you for it.
I hope you don't think that's me. You also provide a service to the community and I respect that. Any complaints I might have with pricing are directed at the distributor, not the retail guys. Your margins are thin, and I know that. And you personally go above and beyond the typical parts vendor with your kits and solutions. Thank you for that. I'm not in a financial position to take advantage of your offers, and/or I enjoy tinkering and finding my own solutions for the problems that you make or invent gadgets to address. Your end results are always top-notch.

May I ask if you still stand behind the Seiken brake booster? I'm in the same predicament and about to pull the trigger even though their prices have gone up significantly from October even. I just can't see paying OEM prices. Thanks in advance for any help and consideration.I've been running the Seiken for 2 years now with no issues after my OEM unit failed (thankfully on the way home from GSMTR, and not during!).
Why do you think the booster is causing soft brakes? What do you mean by soft?
Has your Seiken brake booster met your expectations? Still working well? Am about to purchase one myself.Installed my Seiken yesterday along with Aisin MC. Significantly better braking! View attachment 2334080
