Supertech 6607 Oil Filter: What to Confirm Before You Buy
The Short Answer
The Super Tech 6607 is a spin-on engine oil filter in the Super Tech line, a store brand sold by Walmart. Whether it is right for your car depends on your vehicle's model year, market, engine and sometimes trim. The filter number alone does not confirm fit. Before buying, match it to your vehicle using the retailer's fitment lookup, the original-equipment (OE) filter part number, or the filter specification in your owner's manual.
This guide was not supplied with an official fitment list, dimensions, filter media details, test results or pricing for the 6607. It does not state which vehicles the filter fits. Treat any application list you find as something to verify against your exact vehicle.
Why the Part Number Is Not Enough
Oil filters for different engines can look nearly identical on a shelf and still differ in details that affect safe operation. The same model name can also come with more than one engine, or with changes between model years and regional markets. Compatibility therefore has to be tied to the specific powertrain, not just the make and model.
Details That Determine Compatibility
Thread size and pitch: the filter's center threads must match the threaded post on the engine's filter mount. Gasket diameter and thickness: the rubber sealing ring must seat fully against the mounting surface to prevent leaks. Overall height and outer diameter: the filter must clear surrounding components and fit the available space. Bypass valve setting: this internal valve lets oil flow around the filter media if the media becomes clogged or the oil is very cold. The opening pressure should match what the engine is designed for. Anti-drainback valve: this rubber flap helps keep oil in the filter when the engine is off. That matters most on engines where the filter is mounted sideways or upside down.
Retailers and filter makers usually publish these specifications for each part number. If you are comparing the 6607 with another filter, compare these measurements and valve settings rather than relying on appearance.
How to Confirm Fit for Your Vehicle
Enter your exact year, make, model and engine in the retailer's parts lookup and check that the 6607 is listed for that combination. Find the OE filter part number in your owner's manual or on the filter currently installed, then use a cross-reference chart to confirm it maps to the 6607. If the lookup shows notes, such as a production date split or an engine code, check them against your vehicle registration or the label on the engine or door jamb. At installation, compare the new filter's gasket and threads with the old filter before tightening it.
Unresolved Questions
The material provided for this article did not include the 6607's vehicle applications, physical specifications, rated service interval, filtration efficiency, construction details or cost. If any of these affect your decision, for example whether the filter suits extended oil-change intervals, check the manufacturer's published specifications for this part number. Your vehicle's maintenance schedule is still the reference for how often to change the oil and filter.
