[@jayollom2281]

Nice video, but could you give the part number for the correct bosch plug? You rave about how bad the ngk is then "this is the right bosch plug with the resistor" but never give a part number.

[@figitt88]

NGK the greatest plug of all time ... in all vehicles. But the issue with yours was not the plug brand.... but the fact the old ones were fouled. Plugs of any type dont last too long in a VW due to the rich mixture, rudimentary carb, etc etc.

[@michaellauerman4344]

VW plug cable connectors have 1k ohms resistance already. Why would you want to increase resistance, compromising the secondary circuit? (Sorry. but was VW/Porsche/BMW factory trained early on. Ran a very successful Calif. business for years, in the business for 65 years)

[@drewnashty]

This is a 'Car requires full tune-up' issue or 'old fouled plug vs new plug', not NGK vs Bosch. New NGKs would have had the same results if they are the right spec. By the sound of it and looking at those old plugs i'd venture to guess a full tuneup should have been in order; plugs, wires, rotor, points, cap, condenser, fuel filter, oil, and the ?CARBS? You could hear it even after the new plugs were installed she still wasn't running just right ... I've been servicing vehicles running Bosch or NGK for over 25 years and in all of my own cars, those are the only ones I ever use and never seen a difference between the brands unless they were fouled or the wrong spec/gap. Even on 1000+ hp engines if the plug temperature and gap ain't right detonation and $$$ problems can occur

[@roberthasserd513]

I really appreciate this, I recently replaced the old Bosch plugs with NGK and just like you said I have the identical issues with my 63. I will order the Bosch plugs and get the ole bug running right again. Thanks so much, right in the middle of restoring the bug, it has been sitting in a carport for 30 yrs.👍

[@dmain37]

@@lariolouw5677 Recommendations are to put it under the tank between the tank and steel line. Others put it behind the firewall. Most do have it exactly where you see it. As long as you change your fuel line out occasionally, should be fine. Once the rubber starts to split, then the potential for fire is greatly increased.

[@ARockyRock]

@@lariolouw5677 the engine bay gets extremely hot and the cheap plastic fuel filters in the engine bay are at risk of bursting and spraying fuel directly onto the coil/distributor. you need to be very careful because these old bugs love to catch on fire, pay attention to the fuel line and filter.

[@n4zou]

Back when air cooled VW's were cheap and common as dirt if you used Champion spark plugs when you removed them the aluminum threads would stuck to the plug threads leaving you with stripped spark plug threads in the head's. I had an adapter for my mill just for installing steel repair plugs to fix the stripped threads. These plugs were not simply helicoil thread repair parts but a threaded plug with a flange with stakes that held the repair plug in place. You had to use a mill to install them in a head.

[@tattoojosh1]

This happened to me

[@johncollins5552]

I've been running NGK resistor plugs, BR6ES, but generally prefer Bosch parts. What do you think? If plug resistor type is the key, would any resistor plug do the trick?

[@minicmotorways]

i see so many bugs on KZbin with those plastic fuel filters in the engine bay, they get hot in there & have a tendency to fail quicker spilling all the fuel on the hot exhaust = fire - they should be fixed on the hose as it leaves the gas tank underneath up front - this will also stop any crap getting into the fuel pipe in the tunnel & any slight leakage you will smell it right away as its in front of you as you drive - nice vid though 👍

[@vintage76vipergreenBeetle]

The black bug would run even better with the correct distributor, to match the carburetor. 009 distributors are great for all out racing and spare to get you home.👍

[@DB1Journeys]

I've always used 009 distributors in all of my VWs with no issues.

[@muzzcovw7674]

Exactly! For a stock street car the 009 is an old fad that just refuses to die

[@jschrauwen]

NGK plugs are just fine. Your off idle acceleration issue is due to the 009 distributer you're using. I'd venture to say it's not 100% set correctly as well. It could also account for lack of max rpm/speed but I'd look at possible throttle cable slack. 2. You need to get a vacuum advance distributor. 034 SVDA 3. Your fuel filter is mounted in a dangerous location. It should never be mounted after the fuel pump. It needs to be moved outside the engine bay. 4. Why is there a ceramic resistor beside the coil? If it's old school coil it needs to be mounted upright. Best solution is a newer style 3 ohm coil which eliminates the need of a ceramic resistor and it can be mounted upside down.

[@ericknoblauch9195]

My mother had two VW's. She always had Bosch plugs installed. Also when she needed a new voltage regulator, she always had Bosh installed because the aftermarket ones would only last a week, and need replacing.

[@danielanderson2030]

Ive got an 1100 something in a formula vee im having a hell of a time chasing a seemingly similar issue. Thiught we swapped out to the bosch's but now i need to recheck.... had a massive leakdown bypass so i just relapped the valves back in, then found the #3 intake rocker was hitting on the retainer... cleaned all that up, leakdown was great, but still only makes 125-130 psi and has this sort of lean bog/stutter. And i dont want tobwaste a day tesring the carb apart because the acceleratoe pump doesnt spray very nicely. It just kind gushes out and some of it spurts out the top. Im used to webers and they have a nice solid stream. So instinct is accelerator pump.

And don't get me started on their condensers

[@driveanalog747]

You can get the correct plugs in NGK but I have never had good luck with them. They tend to foul out quickly. NGK's are very good but just don't work in aircooled cars. The other thing I didn't mention is with a resistor it has a longer spark time. I had a viewer give me a hard time about that.

[@billyb6043]

not questioning your knowledge or experience at all, but without explaining why the plugs you removed weren't suitable for this particular engine, no one is the wiser. If the manufacturer specifies a certain type of plug, it is because it will have a specific thread length, pitch and diameter (determined by which cylinder heads you have fitted,) a specific electrode length (most applicable to the design of the combustion chamber in the head), a specific heat range (based on the normal operating temperature range of the engine and prescribed octane rating) and if it's a resistor type plug, a specific resistance (in conjunction with HT leads & caps, to reduce RF and provide optimim spark, depending on the ignition coil fitted. To say that VW aicooled beetles don't run properly on NGKs is nonsense. If everything was bone stock and made to OEM specifications, then perhaps the german made Bosch plug originally fitted are marginally better than another brand, but as you said, this is a relatively new motor, probably has a different ignition coil, leads, caps, points etc, all of which will differ from OEM specifications and create a different set of requirements....besides which, NGKs have a rolled thread form,as opposed to a 'cut thread' which lessens the chances of wearing the threading in the aluminium heads....hence why most engine builders would reccommend the right NGK plug, over and above a Bosch or other brand. I gave up on bosch plugs (made in India) when three out of four new plugs were bad from new...if I'm buying plugs, it shouldn't be a lottery. It's more a case of undertsanding which plug is most suited to your particular set up, hotter, colder, projected, resisted etc etc....it's not so much to do with the brand, in my opinion

Do you really think that changing brands of spark plug was the problem? I noticed you didn't go out of your way to show the old plugs that came out, you just blamed the brand of the plug. I could see both of the plug you pulled out was totally black from the engine running too rich which will foul out the plugs no matter what brand they are. If you don't lean out the fuel mix then your new Bosch plugs will be in the same shape as "the other brand". A fair test to see is as you say the NGK won't run in a VW then you should put in a new set of NGKs on camera & show the world how bad it runs then put your new Bosch in & show the difference. And while we're @ it, gassing on the engine is not the way to show how smooth an engine runs. Thanks for asking!
