TheSamba.com :: View topic - NGK B5HS Still The Preferred Spark Plug For '67 Beetle?

Sat Sep 03, 2016 8:19 am

I haven't gotten plugs for this car before, but I get conflicting results from parts houses on which NGK plugs are right for my '67 Beetle 1500 (stock, but will have Ignitor II and .6 ohm Coil). Amazon says B6HS, Rock Auto says resistor and also lists Iridium, some say extended tip, some say don't use extended tip. What gives? I'm inclined to go with the B5HS.

I've read here that Bosch quality isn't what it used to be.

Should I use anti-seize on these plugs? The NGK's I got for my Honda aluminum head have a special coating and you should not use anti-seize. What about VW's?

I use B6HS. The pro engine builders in the performance forum recommend a drop of oil on the spark plug threads and your good to go.
Good Luck.

:) I like and use the NGK BP7HS (extended tip) that will NEVER touch any piston.

HRVW, The number in the BP7HS is the heat range correct? I can't remember if the higher the number the colder the plug is or is it the other way?
Have a great weekend.

NGK web site says their plugs have a plating on the threads that acts as a release agent during removal and you shouldn't use anti-seize. Anti-seize acts as a lubricant, and the plug can be overtightened.

"7" is 2 grades colder than the stock "5".

I use a BCP6ES. The "C" indicates a 5/8" socket vs the normal 13/16". This is great when you have dual carbs with big manifolds.

That 5/8" socket size would be handy, but it looks like NGK only makes them in the longer 3/4" reach, not the 1/2" that I need.

Luckily my heads are 3/4" reach ;)

A B5HS is the equivilant of the stock W8AC. The BP5HS has the projected electrode, BR5HS has the resistor, and BPR5HS has the tip/resistor. I'd use the BP5HS. Also look for NGK's new numbering system when asking at the auto part stores. The BP5HS is a 4111.

No clearance issues using the extended tip (BP5HS) in a stock '67 1500?

No clearance issues.

I don't have plugs in my dd that long to really worry about seizing. I took the "100k" mile plugs out of Dad's 96 Voyager at 30k, and put silver antisieze on them. Quite a few sets, and 340k later, they always came out. I never had an issue. Antisieze, oil, even milk of magnesia, I wouldn't put them in dry.

:) The NGK number 7 is a colder plug as stated and I always used them in a NEW engine as a starter....no need for hot plug.

Always sprayed WD40 or dipped in solvent or a touch of gas on the threads when installing any plug.

No harm as the plugs always came out easy when a change was needed.....just a matter of choice and/or experience.

When selling plugs over the counter would ask how many miles their engine had so I would suggest a certain heat range for their needs.

Building engines would see all kinds of Spk plugs in a core/exchange.

Thanks everyone. Seems like most use something on the threads, which I tend to agree with. I decided to post a poll.
