Wow! I'm surprised you'd use a K&N-panel-maf-gunker filter. I'm guessing you're saving for a true intake in summer.
1. You need to clean your maf during the early runs
2. Not many people clean it after the year
3. Doesn't give enough sound or gain for the price
Granted... 40 bucks if Canadian, I'd do it... Once.
