logbook,

Tama si Supierreman. I don't sell Simota filters.
It IS NOT a good value for money.
All you get when you buy a Simota filter is a shiny, cosmetically pleasing tube(which has very minimal effect of power gains) & a disposal synthetic paper filter thats made to look like K&N.
You have to wonder about why it costs less than an original paper filter, even when considering the fact that OE filters are "price conrolled".
The price & the tube is attractive but the filter's airflow rate & filtering ability is not.

I sell K&N's because although it may be more expensive initially, the benefits outwiegh the cost.
It has been proven time & again to increase power & fuel economy(0.7km/liter improvement on alfalfameister's Expedition), while being washable with cleaning intervals of at least 50,000kms(for the drop in filter).

For the Mazda Familia GLi & GLX a drop in filter is 3,200. An cone type with carbon fiber top is 4,500. Both are installed prices.
