hello all, Bud's Benz installed new plug wires on my 230sl several years ago and I've often wondered by the #1 wire has a 90 degree elbow on the plug end. Is this plug wire correct for a W113? thanks in advance for any insight...Charles
-
The angled plug wire for the No1 cylinder is incorrect for the Pagoda. It was used for the carbureted in line six. All the plug connectors on the 113s should be the same for each cylinder.
-
That's right. It's angled 90 degrees so it can fit behind the distributor on engines with carbs. This spark plug terminal is often 5K ohms with a carbon core coil wire. If anything, remove the carbon coil wire and replace it with a metal core type.
Almost every car I look at has the wrong ignition wires. The owner orders a set of wires and expects them to be correct not realizing they're far from it and then wonders why their car doesn't seem to run all that well.
-
Yes if you have the correct wire ends, they will unscrew off the wires. If so you can cut the wires to the correct length, as original, so they are routed correctly.
-
This kind of issue with wires comes up so frequently.
Is it safe to say that one CANNOT buy "commercially made" and "correct" plug wire sets for Pagodas?
I know mine were custom made using Beru wire, Beru ends, and all the correct angles--meaning all straight.
The only thing wrong with my wire set (which Dan Caron took care of years ago) was that one of the wires was excessively long; it was the coil to distributor wire.

thanks guys, I appreciate the quick responses. I figured it was probably incorrect for a w113. The plug wires are labeled 'Bosch Ultra-Premium 7MM Opti-Layer Copper Core' so at least they're not carbon core. I'll go through my parts bin and see if I've got a set of plug wires with the correct wire end. thanks again,,charles

Perhaps the easiest thing is to just replace the plug connector for straight one..

Check the coil wire. It may be carbon - most are.

Only correct wires that actually look and perform as needed, are those sold by K&K. You can order sets for 230 or 280SL.

I was looking at these. The 230‘s have plastic plug connectors versus metal ones on the 250 /280. Why is that and what are the advantages?
-
The KK 230SL show the angle connector for plug 1. The 280SL picture looks more like the wires that came on my 1966 230SL.

You are right. I didn’t recognize that. So, according to earlier posts these are not correct ?

I just bought three sets and they're all straight plug connectors. 230 and 280 are the same basic components with the 280 style having metal ends. Full metal core with 1k plug connectors, and no resistors on the coil wire or distributor cap. This will give you a total of 6K ohms at your spark plugs.

Great. Thank you.

Do the K & K wires work with the thin style (4mm I think) spark plug tips or the larger (SAE I think) spark plug tips? TIA Lee
-
You would want to make sure that you buy spark plugs that have threaded ends. I'm fairly sure that's been the MB standard since at least post WW2.
-
OK, many thanks.
-
Where can I buy some KK Plug Wires? I'm not finding them.
Also, my current plug wires on my '66 230SL rub the inside of the hood. Should the proper plug wires have a 90 degree connection at the distributor?
Thank you,

The number one wire does not have a 90 degree bend. It is the same as the other wires. The 90 degree was only used on the carbureted engines.

To the best of my knowledge they were straight. When they are straight they should not rub against the hood. Are you routing the leads under the fuel lines?
-
Jay, here's how mine are routed..

Jay,
K&K is one of the vendors listed in our vendor section. They are pretty well known, particularly for their supply of sheet metal parts.

You may want to call them first; Dr. Benz (Dan Caron) has suggested that "Only correct wires that actually look and perform as needed, are those sold by K&K. You can order sets for 230 or 280SL." however the set pictured on their web catalog doesn't look right, and the price seems very low; I know that the Beru or Bosch metal ends are in the range of $20 each, so that would put the wire set at a cost of more than $120. It's not; so a call is in order to see what they are actually sending you and if its appropriate for your 230SL.
-
Their picture shows 90 degree ends at the distributor cap but that's not what you will receive. They're just simple push on ends without any resistors.

I bought mine from Mercedes in 1995 part number 930-150-00-18 and they are similar to the ones Charles posted but are labeled with "Bosch-7MM Silicone-High Temperature" and has the 90 degree at the #1. They have Bosch metal ends 1 ohm as shown in my picture.
Does anyone know where I can get a straight Bosch metal end for my #1 to match my other 5? Also I noticed that they can be unscrewed from the wire but can't seem to unscrew mine. Am I missing something?
-
I bought them form Mercedes dealer, PN A 000 156 52 10. If they tell you the PN changed - be careful, tell then you need to look at it before you take it.

The end will get stuck on to the wire and you may need to carefully pry it off. I use a small amount of dielectric grease which makes assembly much more easily done. Make sure your coil wire is metal - many are carbon in that type of set.
-
Thanks Pawel! Found on eBay and ordered.
Dan: Is this the correct coil metal core?
-
No, that's carbon core. You can find a piece of metal core wire then reuse the old boots and clips. I'm glad you included a picture so everyone can see what not to use.
-
Yep, that carbon core wire will add an additional 5K ohm resistance to each spark plug circuit. Not a good idea, especially if you are using the old original ignition and coil.
-
Thanks Dan and Joe!
What surprised me the most is that Mercedes sold these type of wires. The coil wire is made up of the same wire that that go to the plugs so none of them are copper core. Joe I read a past post of yours that explained the 19k ohm total resistance for a transistorized ignition which my car has and decided to just purchase new ones that are correct.
I called up K&K and their wires are solid copper core with Bremi metal ends with 1K ohms resistance for the 250 and 280 SLs. Their price is going up 15% starting with their next shipment they get in. But the distributor ends are at 90 degrees. For my car it has the black plastic distributor cap cover so I need straight distributor end boots so I will salvage those from my old wires.
Authentic Classics also sells the plug wires and they appear to be the exact same as the K&K ones for $75 so I ordered a set.
Thanks to all for your posts! One learns something every day about our Beloved Pagodas!

I measured a 14'' piece with my meter and it was over 10K ohms! Not good.......

Interesting Dan, if you think about it, the resistance will increase with the length of the wire?. Cut it in half and check again to verify :) :)

I always was kind of tall for my height.
Resistance does go higher with length of carbon coil wire. Not a problem with a sold core wire.
