Hey guys, I rarely post but read. I just wanted to say, I put a K&N panel filter in my Penastar Journey with E85 and WOW. It FEELS (note: FEELS) like I picked up 25HP. The acceleration response from just the K&N alone is noticeable. I picked up about 2MPG too. Worth the $45 IMO. I'm not some jackass, I understand the skepticism but truly, it feels great.
