first thing DO NOT spray anything into your MAF (mass air flow sensor) you WILL destroy it and unless your lucky and have a good junk yard around the way you will be shelling out quite a bit of cash for this part if you were to buy it brand new.. secondly becarful when cleaning the intave valve as it might have a special coating on the valve itself and can be bad if you rub it off, third if you dont like to replace your air filter get a K&N air filter for your model, they last 50,000 miles be fore you have to clean them ,never need replacing, and add about 4+ horse power..
