I was wondering if you guys would be testing your filter and posting the results?

I was disappointed by the results of the testing posted on this website.

K & N did much worse than I would have expected.

It did much worse on filtration...but flowed overall the best.

 

Intial flow was the best, but it plugged three times faster than a paper element.

K&N is supposed to go 25-50K before needing cleaning.

That doesn' seem likely to happen.

I would like to know if the works filter can beat the stock paper, and have close to the same filter ability.

Seems unlikely, since it is very similar in design to the K&N.

Everybody like to make claims, superior performance, wind tunnel tested, ect.

But when challenged nobody has data.

The testing site has good data, and that is the only place I have seen any.

You'll have to decide if it's worth it for 5 more horses

 

Filtration wise, I'd expect the Works filter to be similar to the K&N. I'd also expect it to be similar power wise. For the relative gains in power we're talking about, it's all about the same.

It's all just a trade off though. If you live in a very dusty area, maybe stay away from the oiled filters. Or, change your motor oil often as that's where most of the contaminents end up.

 

wow. my perception of K&N has just been skewed...

 

We've flow tested the WORKS filter vs. others and were pleasantly suprised to come out on top (even foam-based filters that don't filter as effeciently). As far as filtration, most other companies are using a cotton gauze. If you're familiar with it, you'll notice that the openings on the gauze are highly irregular and some are huge (relatively speaking). One of the things that sets the WORKS filter apart is the fact that we use a cotton fabric. The openings on the fabric are both regular and consistent in shape and relatively small in size. (You can get somewhat of an idea by looking at the your clothing.) This allows the WORKS filter to both breath efficiently and filter effectively. We're not big fans of extended-interval maintainence for any item on our vehicles and this is exemplified by the cleaning schedule we recommend: roughly with each oil change, not with each timing belt

 

Thanks for the reply.

Flow testing is an easier test than filtration.

I wonder if you could post the results of the filtration testing if you have done it?

I think your products are better designed than most of the stuff out there.

If you can show good flow with good filtration, then your filter would be a win win product.
