I had a post in the old regarding this, you have gotten the part number there, anyway here is the link again to read if you haven't
http://clubisuzu.proboards.com/index.cg ... 396&page=1I think mentioned to measure your old filter dimension and then go to the K&N web site and double against 1009.
The reason I say to check is that there are a few different size air boxes out there, as I found out the hard way. Don't go on what a web site or book says for a MU, actually take out the paper one and measure it or hand it to the sales person.
I know that my K&N filter is the above mentioned, good like finding someone who has it in stock, I got mine shipped from the states,...took 2 months.
When I get time I'll do a FAQ on Standard vs K&N air filters.
