ok so i am thinking about buying an FIPK kit for my moms Expy. what do you guys recommend? what gets the best hp increase and best gas mileage increase for under $400? i appreciate the help if i get any!

 

Holy cow, $400? You could just about buy 2 of them.

I have Airaid. Many have K&N. Airforce One are great as well. AF1 may get a slight nod on performance increase. I'm going by what I've seen Mike Troyer post about them. AF1 is what he decided to start selling. They also have a polished SS tube. You can click on the link at the bottom of my sig to see the Airaid.

You can get any of them form the Online Store, or the AF1 from Mike Troyer as well. Either way you'll be helping to support the site. I got my Airaid from Roger at the Online store.

 

hey thanks ill be sure and tell my mom what i found hey i like your site too! the gibson sure does sound sweet on your Expy. do you like it? well thanks for your answer

 

I bought the Airraid from the online store and love it!
