* Auto Parts Stores: Local auto parts stores like AutoZone, Advance Auto Parts, NAPA Auto Parts, and O'Reilly Auto Parts are good starting points. You can check their websites or visit in person. Provide them with your vehicle's year, make, model, and engine size. They may have a direct replacement or a compatible aftermarket part.
* Online Retailers: Websites such as Amazon, eBay, RockAuto, and Summit Racing Equipment offer a vast selection of auto parts. Again, be sure to specify your vehicle's details accurately. Pay attention to reviews and ratings before purchasing.
* Dealerships (Chevy/GM): A Chevrolet dealership will have the genuine GM part, but it will likely be the most expensive option.
* Junkyards/Salvage Yards: This is the cheapest option, but requires more effort. You'll need to locate a 1992 G20 van with a 5.7L engine in a nearby junkyard. The condition of the used hose should be carefully inspected.
Before ordering: It's crucial to identify the *exact* part number of your air intake hose. Sometimes there are multiple versions depending on the specific trim level or options of the van. Checking your owner's manual or a parts diagram online (some parts websites have these) may help you determine the correct part number. If you can take a picture of the hose, that might also help auto parts stores find the correct replacement.
