Air Filter Replacement
|Best Place to buy:||Typical places, even most part stores carry it, if you're in a bind.|
|Cost to Have it done in a shop:||$|
|Special tools needed:||none|
Open it up, replace, shut it.
Tip: What I like to do is get a Sharpie Pen and write the month/year on the filter itself, just in case I forget "when was the last time I changed this" kinda thing.
UPGRADE: If you think this huge airbox is inefficient, you are correct. Try the After Market Intake Installation upgrade.
