Yep. Idle for 2-3 min. before you shut it down. Get the oil changed at 3k miles and on your 2nd oil change, switch to a synthetic or synthetic blend. This will help keep the turbo seals from committing an early suicide. I run regular oil with Lucas Oil additive for the last quart. Cheaper than full synth, but you will get the same benefits as full synth. No matter what oil you decide on, get it changed often! This engine will cook any oil rather quickly. Cooked oil is great for french fries, not so great for high hp 4 cyl turbo cars.
I got my Injen cai for $237 shipped. Surely you can scrape up this small amount of money. It will free up the airflow so much! Better mpg too. Sound great tons more power and was really easy to install. (less carbon on the tailpipe too)
