I was just posting this for everyone to post good ideas for those small, cheap, or easy performance ideas to do to your Zuk. Perfect for the budget, non-mechanics, or lazy people.
My only one was using an open K&N cone filter on my Tracker. The drop in ones dont do much. My friend has the 99 2 door vitara with the 1.6, I have the same engine basically. My K&N did much better then his drop in one did. Part number RU-3610. Me and AJMBlazer will stick by this upgrade.
