Hello,

Just wanted to post some information about an air filter I purchased from the internet.  I installed a 'Hiflofiltro' as an air filter which is supposed to be equivalent to the air filter that came with the bike.  Note the brand name is a bit confusing because this is just the name; it is not considered to be in the class 'High-Flow Filters'.

One thing I noticed that was very different was the filter was pleated about 35 times compared to about 12 times on the OEM Suzuki filter I had pulled.  Was this done to catch more?

Seems like a good filter so far, though I'm not sensitive enough to my bike's condition to be able to tell if it is less restrictive.  I know the company's website claims the filter does not necessitate re-jetting.

More pleats equal more surface area. All things being equal, thickness of filter media, efficiency of the media, I.E.,what size stuff does it stop, that is a better filter for a coupla reasons.

The more pleats, the easier for the engine to inhale, because it's drawing through more surface area. Think big straw versus skinny straw and a malt,  And,, more air goes thru before it needs cleaned.
