As decades wore on, the fuel injectors on your van wore out. Their pintles were damaged and dirtied by debris in your fuel and fuel tank. The hose nipples were scratched, the brittle plastic ends cracked, and the flow rates drifted askew. Rebuilds bought them more time, and at GoWesty we continued to source the best reproduction injectors to deliver fuel exactly as VW had intended. But eventually, 40 years after Bosch laid down the blueprint for your injectors, we could no longer find anyone that could keep this ancient technology alive. Luckily, our friends at DeatschWerks are wizards with fueling systems. After a long effort, our work with DW has resulted in a dramatically improved, modern replacement for aging Vanagon injectors.
In addition to their overall much more modern design, these GoWesty, brand new injectors adhere to a much tighter overall flow rate tolerance than the original Bosch design using multi-point dynamic flow testing. On top of that, each set of four injectors is a matched set so are within +/-1% of each other at all flow rates. This ensures that all your cylinders are getting the correct and identical amount of fuel whether you're idling at a stoplight or standing on the accelerator to get up a hill.

The bottom line is: These GoWesty injectors will provide the best possible fuel economy, power, and reliability. If your Vanagon is feeling sluggish, experiencing a rough idle, or getting poor fuel economy, and a normal tune up hasn't helped, we'd highly recommend a set of these injectors these injectors to pep up your Waterboxer.
Fit: These injectors will work with any 1983-91 water-boxer Vanagon, including MV and DJ engines. See the 'Fitment Notes' tab for important installation notes.

No core charge: These new injectors are sold outright. -0-280-150-206
Note that the retaining ring on the body of these injectors is a bit different than on the OE part. When installing, make sure that the inner lip of the provided large end injector grommet fully seats into the injector body to hold it in place.
Caution: the Bosch-design electrical plug that this item accepts is the same as on many other components in the engine compartment, some that are close in proximity to each other. Be very careful not to mix them up! Always unplug/plug in one thing at a time whenever possible, label all plugs if more than one is to be removed, for example when replacing an engine long block, or even just the throttle body.
NBR (nitrile butadiene rubber) Fuel Line. Designed for safely conveying gasoline, E-85, diesel, and bio-diesel fuels. Handles temperature ranges of -40 to +257 degrees F. Withstands oil, grease, abrasion, and ozone.
These injectors are backed by a one year/unlimited mileage warranty.
Important note on a clean fuel delivery system: All fuel injectors, including your new GoWesty injectors, are highly sensitive to fuel contamination. Dirt and grit in your fuel—from a rusty fuel tank or from dust intrusion during installation, for example—can prevent the injector from flowing at the correct rate, closing fully, or (in extreme cases) can entirely clog the injector. This is, in fact, the main reason injectors have to be replaced—and probably why your old ones were replaced. To ensure that your new injectors do not suffer the same fate, we strongly recommend you verify that your fuel system is clean and, at a minimum, install a fresh fuel filter and flush out ALL the lines between the filter and injectors and make sure there is no possibility of dust or dirt intrusion during installation. (It is a good idea to install the injectors on thoroughly flushed fuel rails on the bench where you can maintain the necessary sanitary conditions required for the job).
Every single one of these injectors is tested on a flow bench, so we are 100% certain they are working correctly when they ship out of GoWesty in a sealed box with a flow report included. Therefore, we will not warranty injectors that have symptoms related to fuel contamination.
