@@danlively Id put the stock ones in for warranty work. It’s an easy swap. But I think Kia calls for them after 30k miles anyway if I remember right. It’s a maintenance item anyway so doubt it would cause issues if you left them in

Can you tell me all that you did to your car besides the shark intake and the Jb4..

I got the the all-wheel-drive it's hard to find lowering kits but I have seen one.. just grabbed a 2023 K5 GT line. Looking to do the stuff that you did. Just driving this car back and forth to work cuz it's the longer drive than using my diesel truck.. any info would be great ,, and anything new let me know

@@zstampe Thanks for the info

[@__007__]

@@patallen8589 how much faster does it feel with the jb4?

[@TastySurrealBowl]

I’d be really curious what this mod does to the longevity of the engine. It wasn’t engineered for the increased pressure, heat, etc. I have the same vehicle as my daily driver and the reason I bought it was that the stock programming in the available drive modes gives me the economy when I want it on the highway (I pull 47mpg on long hauls), yet the torque off the line in sport mode when I want it, all stock. If you start modding it this way is it worth the potential loss in longevity of the engine that pushing it past its original design specs causes? Buy the GT and put snow tires on it if you want the added traction (or whatever motivated the desire for an AWD GT-Line). I got the FWD option (which is 300lbs. lighter) and put Blizzak WS-90s on my GT-Line in the winter and there was nothing I wasn’t able to drive through seamlessly. The extra weight of the AWD hardware isn’t worth the loss in fuel economy and pick up off the line.

[@zstampe]

Lots of guys running the JB4 for many many miles. I could’ve gone Gt but I’m not a huge fan of the DCT in them. You say it wasn’t designed for the extra pressure, but it is basically the same engine as the forte GT which has higher boost than our cars. I’m running a pretty conservative map and don’t race the car either. But you also make good points. Thanks for the comments.

[@el34glo59]

47 mpg? Jesus that good. You think i should pass over the AWD? I live in jersey. Thanks

[@TastySurrealBowl]

@@el34glo59 It really comes down to personal preference, but I live in Michigan and in rural areas winters can get really hairy in the winter, so whether I’ve owned AWD or FWD I always run Blizzak WS-90 snow tires in the winter. Even AWD with all-season tires will never perform as well as good snow tires on either drivetrain in bad winter weather. When the roads get bad I drive conservatively to minimize issues, but when the roads are grippable (the vast majority of the time) I prefer the lighter weight and less hardware to move down the road that the FWD option offers (and the big MPG gains when going long distances on fairly flat terrain highways). Don’t forget possible long term (after warranty) maintenance expense for the AWD hardware (rear differential) if you plan to keep it long term. Keep in mind that the 47pmg only happens when I’m on a long stretch of highway that doesn’t involve a lot of hill climbing. When I’m driving around the city (traffic) and in mixed driving, I’m averaging about 37mpg. I just met someone the other day who commutes on the highway daily and he said (unsolicited) he is averaging 47mpg daily in his FWD GT-Line, so I’m happy with how the FWD has worked out going into my 11th month with it (after 4 full seasons of driving in every condition). The FWD with snow tires setup did excellent in bad winter weather for me, but it comes down to your specific priorities. Good luck - either way you’ll love the K5 GT-Line! A lot of features for the price.

You can change maps based on what fuel you want to get. You can’t run any of them with 87 though. 91 you can run map 1, 93 map 2 and you have to have e30 for map 3 which is 93 with a couple gallons of e85.

You need to be shifting at 4750-5000 rpm. From 4750 rpm to 6000rpm you only gain 2-3 HP but you lose 50 ft-lbs of torque. That last 1200rpm slows you down. These motors do not make anymore HP after 5000 rpm and torque falls on it face very similar to the early N55 BMW motors.
