I'M STILL PRETTY NEW TO THE SITE BUT I KEEP READING ABOUT THESE K&N FILTERS AND HOME MADE SET UPS. WHAT'S THE PURPOSE EXACTLY AND WHAT'S THE BEST WAY TO GO? I HAVE A 98 4.6 AND IT LOOKS PRETTY EASY TO GET TO THE COMPONENTS, I'M JUST NOT SURE WHAT HAS TO BE DONE AND WHY?? ANY FEEDBACK OR SITE NAMES THAT EXPLAIN IT ALL WOULD BE APPRECIATED. THANKS AHEAD OF TIME.

Please turn off the caps, thanks. The purpose of the K&N Airfilter is to give performance by allowing more airflow. Thats exactly what the FIPKs do, they allow more air to enter the engine.
