Monark vs. Bosio nozzles - PeachParts Mercedes-Benz Forum

airedale2 · #1 12-12-2007, 02:54 PM

Any body know the differences between the two. Curious if the monark are nozzles are factory spec bosch(quality) or enhanced like the bosios. Am currently looking at the two, and $200 vs $100 for possibly the same nozzle leaves me some definite wiggle room.
thanks

I would use Bosio or Bosch. Never heard of Monarch.

Apparently the monark nozzles are manufactured in germany. They are supposed to be oem quality, but so is Fram. One other person on this forum has used them with good results. I am more interested in the spray pattern quality/improvements over stock. With bosch's decline in quality and manufacturing in India, I thought i had read that bosio was manu facturing in India as well. Why buy Indian made Italian nozzles when i could get german at half the price. ANY input would be appreciated.

Thanks for the info. I have to agree with you line of thought.

I can't speak for Monark nozzle quality first-hand, but a few people here should be able to. Suggestions have been made that they may not be any better than the MICO Bosch parts made in India, (Non MB parts.) However, initial satisfaction with them seems good from the non-MB crowd, as well as the MB owners. If you're up for experimenting, give it a shot. Nothing ventured, nothing gained.

Don't buy their glow plugs, though. Those get a definite "F" grade from just about everyone.

Do report back on how they've performed after many miles. Most Monark nozzle references among MB users seems to end with, "It runs great now. I'll post about how well they hold up." Then we never hear about them again. Heck, even the India nozzled cars usually run great at first, so that's not a good basis for a purchasing decision. Frustrating, wouldn't you say?

The bosio nozzles are definatley made in Italy....it says it all over the packaging. And they work very well. I've been running them for about 8k now....4 months or so. Excellent nozzles.

From the internet searches that I have done:
Monark users claim OEM quality the way it used to be (not the OEM India quality) and a quieter idle. The adds always say replace as a set indicating to me that there is some differance in their construction (perhaps how the pintel is ground or the nozzle hole size).
(I a guessing but the nozzles from my car have a tiny hole cross drilled at the base of the part of the pinte part that protrudes from the injector nozzlel; maybe the Monark nozzles do not have that extra hole in the pintels.)
Bosio nozzle users claim better than OEM quality and better "seat of the pants" performance when you step on the pedal and a little more or no reduction in noise at idle.
I have only read one bad article and it was in this forum concerning Bosio nozzles. The member had 1 of a new set of nozzles go bad and returned it to the Bosio rep. in the US and was told it was caused by the WVO use.

What most who have the old SD 240 design are seeing is the pilot injection hole. The purpose was to quiet the engine, and it did. BUT, this was designed when the rest of the car was not as well insulated as they became by the mid 1980s. The trade off is more fuel consumption and emissions.

The 240 design was updated to the 256, 261 and the last is 265. In some German manuals and catalogs each subsequent number is listed "for retrofit of previous" or something to that effect. I also saw one footnote for the SD 265 - "suitable for use with vegetable oil" but I was not able to cross reference that.

Monark are stock design, ISO 9001:2000 and TUV certified.

I agree, Badger should get together with Trunk Monkey.

I have chosen the monark nozzles. Mostly because they are German manufactured. Not that i am not impressed by the comments from others about bosio nozzles and their performance gains. I will not deny that bosio is a quality product, I am not willing to pay more when i do not have to. I did a lot of research before making my decision and do not make decisions litely.
I appreciate all of C Sean Watts input as it was very helpful in solidifying my decision.
I think that any new set of nozzles will be an improvement over a set with 200kms on the clock. I also expect to see an improvement in acceleration since these nozzles have had several updates since inception.
I think CSW has a lot of valuable information regarding this product and that should anyone else request info on these nozzles, he is the man to ask. I only wish i had gotten your email earlier CSW as i had ordered a set three hours prior to recieving your email.
I will follow up on these nozzles later.

Lastly, i will say that one of the influencing factors about these nozzles is that they are german made, and italian made in india(as i have heard about the bosio fratelli).
However, this is one persons opinion.

Got my new nozzles(monark) in 2 days ago, and put them in yesterday. Wow. My car was a slug off the line with 267,000 miles. Not any more. Gets up and goes very quickly with very little throttle. Again, very quick off the line. The one thing i did not realize, is how small the nozzles actually are. Very quiet and very smooth. No smoke on acceleration that i can see. Car runs much quieter on the freeway and much,much smoother. Probably using half as much throttle to do the same. Also noticed transmission shifts much smoother than before also. Nozzles were packaged individually in a sealed hard plastic container with a lid and prelubricated. Immaculate machining. Glass finish on the nozzles. 125$ for a set of 5. One thing I noticed is that i a few different nozzles. Not to say that they are not set at the same pop pressures. Pintle tip is smaller than the head of a needle.
Would highly recommend these nozzles to any considering new nozzles.
Drive diesels from cats, detroits, and powerjokes.
Very noticeable improvement.
Best of all, $125 for a set.
