  1. 4th Generation Optima (2016 - 2020)
    Just curious about that, folks. Zero issues with this car with regular fuel (always use Shell or Chevron), thankfully, but just curious if there's any noticeable difference with premium, like it's the case with most turbos. I was surprised not to see any reference to premium fuel in the owner's...

    I have a '12 SX and I'll need to decide whether to keep it beyond the 10yr/100k powertrain warranty. Have many engines been failing despite passing the recall test?
  3. 4th Generation Optima (2016 - 2020)
    Hey guys, trying to decide if I should keep our 2016 Optima SXL with almost 17K miles my wife drives, or get rid of it. I was disappointed of it before receiving the letter about conn-rod bearing damage that can be 'excessive' (like if any was good), due to increasing oil consumption (1/2-qt...
  4. 4th Generation Optima (2016 - 2020)
    Hey guys, I own the Aussie spec 2.0T GT and considering the Lap3 Uncle chip. I've read a lot about these in 3rd gens and 4th gens with the 1.6T. But I'm just wondering about anyone's experiences with this on the 2.0T engine please. I already feel the car is pretty responsive and already...
  5. Engine and Technical Discussion
    Just saw the new engine recall, and the newest manufacturing date was 05/14, and my car is 09/16, so I should be in the clear on that front. Just wondering if I should stick with the recommended 5/30 oil (M1), or use the M1 0/40 I use on the Porsche, based on higher turbo temperatures. Have...

    Since it was revealed that the 18 Sonata 2.0T is getting an 8 speed automatic. Can we assume that our Optima will also get one? Hyundai Sonata Gets Eight-Speed Auto, New Design | Automobile Magazine
  7. Engine and Technical Discussion
    Anyone looked into this? When I first looked at Optima's in 2011, I wanted an LX with the 6 speed manual (I've always loved manuals). I was basically told the only manual LX available was over 1000 miles away. I was in a "buy now" mood, so I went with an auto. Fast forward to now, I have a...
  8. Engine and Technical Discussion
    Hi all, ive been looking around and have read i think everything on transmission drain/fill for my optima.. But what fluid is everyone using to fill with? Does everyone just use the OEM from the dealership? I would rather not if there is a good aftermarket that works well. Like the title says i...
  9. 4th Generation Optima (2016 - 2020)
    Has anyone installed a pcv catch can in a 2016 2.0T yet? Since the pcv valve is in a different location I thought I'd ask since I haven't seen pictures for a 2016 install. Is the hose diameter larger than earlier models too? I didn't pull the hose off to verify, but it looks like it could be...
  10. 3rd Generation Optima (2011 - 2015)
    I recently bought one of FLIR ONE Thermal Imaging Camera Attachment for iOS and Android these and wanted to see what the 2.0T looks like after about 30 minutes of hard driving in 101 degree temps. Enjoy, and no Dino, no dirty looks. :P https://www.youtube.com/watch?v=NVpBhvakjB0
  11. DIY : Engine And Technical
    Well I went ahead and made an intake for my SXT. Made it from a stainless pipe and mild steel bungs with two barb fittings and an injen Filter. I will be running the bov open so it's not recirculating back into the intake. Materials needed.... 90 degree 3" pipe. $20-$30 90 degree 2.5" - 3"...
  12. Engine and Technical Discussion
    Hello all, been lurking a while now preparing for all I can with performance upgrades for my 2015 Kia Optima SX Turbo. I have a few questions, bear with me as I'm still new to this scene. 1. For oil catch cans, is one good enough or do I really need two. 1A. Which brand works well with my car...
  13. Engine and Technical Discussion
    Hey guys as the title mentions, which is the best intake made for my car out there? I searched around a little bit but came up with a lot of different answers. Thx
  14. 3rd Generation Optima (2011 - 2015)

We are replacing a 16 year old suv (explorer) with 130k, that we bought new, no issues with it, still looks good but just tired of the same car and want an update for my...

    Title sais it. Had it on eBay . Buyer was a 0 post flake. Had it on my car for a weekend to make sure it was all good since I bought it used. Works great sounds great just to aggressive for my girlfriend and mom when they ride along lol. I had picks of it when it was in the car but that phone...
  16. 3rd Generation Optima (2011 - 2015)
    See link: Audi reveals 'rightsized' 2.0 TFSI engine for next A4 What I'd love to see is Kia re-doing something like this for our awesome 2.0T, specifically the Miller cycle, the upstream FI, etc. Then by a "Mode" button, the ECU could have several useful modes: Economy, Normal and Power. In...

    I have looked everywhere for this topic, cleaning our Manifold Absolute Pressure (MAP) Sensor but I am not finding anything (this is the sensor on top of the inlet). I took it off today and saw it was rather oily and dirty. Any thoughts if I need to clean it and what product do you use? I have...
