Hi
Want do you think about these two products :
http://www.autoanything.com/products/product_gnn.aspx?p_id=2090&se=k&n_air_filters (http://)
and
http://www.tornadoair.com/ (http://)
More mpg & power available ?
Any experiences before/after are welcome
Chris.

The Tornadoair is crap. Don't waste your time.
The K&N filter may allow the engine to breate a little easier, but you likely will see no performance or mileage change. There was a thread a while back regarding K&N filters and our vans. You might try a search in this and the sister forums for it.

My 2 cents as an engineer with 17 years of industry experience....
Any turbulator or other type device in the intake is a farce. Think about it - if a cheap piece of plastic would actually improve fuel economy, all the major OEMs would add it in a second. Actually, you don't want turbulence in the intake stream - laminar flow is less restrictive.
On the K&N filter, you can probably measure a small difference in the lab, but it is probably unnoticeable in actual use. Lower restriction likely means less filtration also. K&N is a good company, don't get me wrong, but claims of significant performance improvements are a stretch if you ask me.
Other posters have comments? Glen

I've had a K&N air filter in my 2002 Venture since late 2002. There is no noticable performance or mileage difference. But it has saved me the cost of paper filters.
On a side note, I have K&N filter in my 2001 Denali XL which has a 6.0L V8. On this vehicle, my gas mileage has increased 1 MPG city & almost 2 MPG highway. Doesn't seem much, but it works out to ~12% increase in fuel efficiency.

You wash and reuse K&N filters. A $10 clean/oil kit will last 3 years at least. The filter itself has a millon mile warranty.
