 Is it possible to use a napa 4003 fuel filter as a suppressor on a firearm?

Yes. It is possible.

Most people may think that a napa 4003 wix 24003 filter’s only potential is to remove contaminants from engine oil, transmission oil, lubricating oil, or hydraulic oil. However, solvent trap and fuel filters can be used as an alternate gun suppressor. The good news is that it is cheaper than the actual suppressor and people can do it by themselves at home.

Yes, Wix 24003 fuel filters are viable as suppressors on firearms with the correct thread adapters, especially on small caliber pistols or rimfire rifles. However, there are a number of technical complications with using oil filters as suppressors:

The way that oil filter suppressors get a hole for bullets to exit from is by shooting a bullet through the end of the filter with the first shot. This means that the first bullet fired through the oil filter contacts the metal of the oil filter, which consequentially causes the bullet to deviate from its expected trajectory. This doesn’t matter much at short range, say inside of 50 meters, but as ranges increase, deviations in a bullet’s expected point of impact increase as well. In addition, subsequent shots are less likely to be accurate as they brush by the hole created by the first shot.

fuel filter suppressors degrade rapidly from the muzzle blast of each shot being fired through the filter. Even with small calibers like .22 Long Rifle, broken pieces of the insides of the filter will start spitting out the end of the filter after a few dozen shots and the effectiveness of the filter’s sound suppression will degrade. This means the oil filters themselves become a consumable item that needs to be replaced periodically overuse. While oil filters aren’t exactly difficult to procure, they are rather bulky, and carrying spares filters in a pack or on load-bearing equipment becomes a rather serious exercise in gear management.

Using sighting systems with oil filter suppressors becomes challenging since oil filters have a large enough diameter to obstruct the view of a target through most types of sights unless the sights have a height-over bore distance greater than 1.5–2 inches (3.81–5.08 centimeters). Iron sights on all pistols and most rifles become useless. Telescopic sights are barely usable. Low mounted red dot, holographic, and unpowered reflex sights are usable, but only with both eyes open as occluded eye gunsights where the shooter’s binocular vision is used to superimpose the sight’s aiming reticle on the target with one eye looking at the blocked reticle and the other eye looking at the target.

NAPA 4003 Fuel Filters may affect accuracy.?

Oil filter suppressors are only temporarily effective with small-caliber weapons. Those weapons don’t produce a particularly large volume of muzzle blast in the first place.

The oil filter suppressor installed on the end of the barrel has a big heavyweight. Then the harmonics of the barrel will be changed. And the bullet’s point will be shifted dramatically downwards. This kind of phenomenon is similar to rifle barrels mounted by bayonets.

Through shooting a bullet through the end of the filter with the first shot, the oil filter suppressor will get a hole for bullets to exit from. The first bullet contacts the metal of the oil filter, resulting in that the bullet to deviate from its expected trajectory. The bad result is not obvious at a short-range, such as 50 meters. But if at 600 meters, every single deviation in trajectory angle will cause a huge shift for your point of impact.

Due to the volume of muzzle blast generated by the firearm, the oil filter also is going to degrade. Maybe after 10 shots, pieces of the oil filter will start flying out with the bullets. Finally, the oil filter suppressor will be blown apart.
