Need air filter help
I've recently invested in a K&N filter to replace my air box. I took out the box and attached the filter, theres also another port on the bottom where the air box was and my engine and service lights are on now. And when i hit about 3500 rpms my gear switchs really bad, and acceleration is horrid. I need some help. What should i do? If you need a pic of what i have so far, let me know.
