Well, not today, but last year swapped out factory air filters for K & N filters.
Had them since Jan. 2020, but waited for o.e. to get dirty first.. haha. they still weren't so dirty when I took them out.
Never did get to the track before the swap, so I can know a before and after on 1/4 mile runs... I suspect they'd help a bit for sure.
just 0-100 runs I've done sine, I get a we bit faster times, just a wee bit, but I suspect more effective in 1/4 mile.
Will eventually get some GT and Stinger
badges to swap out too... I don't like the E and L ones. i don't get those ? E for excellence or what the heck does it stand for ? and the L looks like a Lexus, so that's kind of dumb too.
I saw one in my town the other day and I assumed it was a Lexus, until 1-2 seconds I realized Dah, it's a stinger.. oh yah, that stupid L
badge... No weird ones for me.. It's a Kia and a Stinger so a fancy K or S is cool but E and L ?? or a logo of an animal or a lighting bolt or some cool logo...
Anyways. no offense to those who go with them, but I just don't get them ?
