Weight & Inlet Holes

K&N has quite a large bottle but the weight is surprisingly lighter. It weighs 14.1 ounces/400 grams. The base plate weighs 6.3 ounces. It weighs 15.45 oz/438 grams. The base plate weighs 212 grams.

Then, K&N has 8 inlet holes and a plastic inner cage. The inlet holes come in a unique design. They are partially open with a piece of metal inside. On the other hand, Mann has 4 big-size inlet holes with a lot of grooves and a bypass valve down below.

O-Ring

The O-ring of K&N is a nitro rubber material that comes out easily. So it lacks rigid sticking to all the edges. Moreover, the thin gasket isn’t that helpful either. There are mixed statements considering the gasket of the K&N performance gold oil filter review.

Some users reviewed that its oil pressure usage is quite satisfactory despite being thin. But the nitro rubber gasket of Mann is firm and thick.

Filter Media

The filter media of K&N contains 58 pleats of synthetic blend media with some generous space between them. And there are metal end caps on both sides of the pleats. The seam is glued inside. The pleats are quite thick, which is actually good.

As for the Mann, there are 92 pleats with a metal crimp seam and metal end caps. That is too much to get at this price! Definitely, this is one of the oil filters with the maximum number of pleats. Plus the filters are comparatively very deep, almost around .77 inches.

Leaf Spring

We found the leaf spring of K&N clumsy as it barely manages to hold the center. The stamp leaf spring comes in a unique design. We found it cool as it looks more like a drone or a ninja throwing star. As for the can, it is thick and sturdy.

Valve

K&N has a silicon drain back valve to cover up the holes. The bypass valve is quite large. The cage works better for smooth oil flow. However, you’d get better filters at this price in the market.

On the contrary,  Mann includes a moderate bypass down valve. There is also a metal core inside with holes. A lot of threads keep binding inside. There is also a j-back silicon spring drain back valve. A number of Mann oil filter reviews say that it has oil in it to look all shining and glazing. Maybe that is kept like that to avoid rust.

Date Code

The date code of K&N is naturally visible, just like any other oil filter. You either get it in the packaging or at the top of the bottle.

However, a fun fact about Mann is that you cannot see the date code with naked eyes. You need a UV light to view the day code on the top of this oil filter.

Filtration Number

K&N claims to provide protection of 20000 miles and has a dirt removal efficiency of up to 90%. Moreover, its filtration number is down to 30 microns.

However, we couldn’t trace the micron rating as well as the filtration number of Mann. It was mentioned neither in the packaging nor on the bottle. That was a bit disappointing though. But its excellent performance surpassed this minor inconvenience.

Cost

K&N costs around $9-$10. In comparison, Mann costs around $10-$11. And this oil filter is especially for Volvo gasoline engines.
