Unless I'm mistaken the 2.1 WBX uses a 3/4-16 oil filter thread?

Seems odd that being German made it uses an Imperial thread?

Can anyone confirm?

I'm going to order the Glow Shift sandwich adapter for gauge hookup.

Thanks!

you are correct- I am building an external oilfilter, cooler setup and that is the correct size

I suggest adding a couple replacement o-rings to your order if you haven't already. The plate can shift when you remove the filter and then you want to replace the o-ring. Cheap and you'll want it if you need it.

Great thought!

I use only genuine VW cooler seals and carry an extra, what's another Oring or two onboard?

sure you don't want a thermostatically controlled oil cooler adapter in that location instead?! i put in a Mishimoto with a homebuilt cooler and love what my gauges are telling me.

picked up oil temp replacing the oil pressure relief spring cover with one threaded for an adapter, much nicer to get out anyway with a wrench vs a flat blade. oil pressure i get by bringing a T topside of the engine from the 3-4 sender using a grease gun hose.

I believe that if you want to get pedantic it is M20x1.5 but it is equivalent to 3/4-16.

I went out with calipers and thread gauge. I misspoke before. It is 3/4-16. I'll edit my prior post to avoid confusion.

Spin-on oil filters got their start on the west side of the pond so the "English" 3/4-16 thread became the standard. For decades the Motorcraft FL-1a filter, its Chrysler, and its equivalents was the most common filter on the planet.

From: http://www.secondchancegarage.com/public/purolator-oil-filter.cfm

Quote: WIX invented the easily detachable 'spin-on' filter in 1954. Automotive historian Matt Joseph believes Chrysler may have been first to use them. This subsequently became the prevalent design, though not always standard equipment. This type of filter is used almost exclusively in modern cars and in recent years, has gained use in heavy-duty vehicles. Spin-on filters replaced cartridge-type filters that had to be placed in a special canister.

During 1950s, the use of oil filters on cars varied. As early as 1953, a full-flow oil filter was listed as standard equipment for Lincoln V-8s, but a canister type oil filter was optional equipment on the 1956 Ford. The 1957 Mercury included a spin-on oil filter at no extra cost. All 1958 Buicks came with an oil filter. However, if you bought a 1959 Chevrolet, the car and engine you ordered determined whether you would get an oil filter and what type it would be.
