Just had a random idea, want to see if it makes sense: Basically, would installing a pair of air scoops at the lower bumper, with hoses ducted up into the stock airbox/ending right next to the CAI appreciably cool incoming air to the engine/improve performance by any appreciable margin...

I would like to provide power from dome light to windshield mounted radar detector (Uniden R7 with RJ-11 plug) and dash cam (Auto-Vox D6 Pro with micro USB plug). Radar detector runs off 12V, the cam needs 5V, 1A. My rear view mirror has no power. Is there a way to do this simply or due to...

Spotted this on the Concept3 website: https://www.concept3performance.com/collections/quantum-solenoid/products/quantum-solenoid-for-kia?variant=31655958184002 I noticed there isn't one for the 2.4L NA Engine, but that's for later... My biggest questions are: What exactly is this gizmo, and...

Here's a weird one: would it be feasible to create an intake cooler with an array of thermoelectric Peltier devices? Here's how they work: The general idea would be to put the cold sides arrayed in rings down the length of an intake pipe, maybe three or four rings, with the hot sides equipped...

Hi guys. I've been scouring the threads for hours and have come up with a couple of possibilities of my issue. I'm hoping someone had the issue and can steer me in the right directions to the next steps. A few days ago the passenger side mirror on my 2014 SX-T didn't unfold when I walked...

Back in the summer, my left power folding mirror would no longer fold and the motor would just keep on trying. It even would keep making a sound with the car being off. I ended up just unplugging the mirror. Last night for the first time since the summer, I pushed the mirror button on accident...

So this has happened twice now. Both times it was really cold (15 degrees today). It starts fine, but when I push on the gas, it goes but there is a severe loss of power... like I'm guessing it would take me a good 30 seconds or more to get up to 60 mph. On both occasions, a restart fixed it...

I have a 2018 Optima sx turbo. I was in a grocery store parking lot yesterday. When I returned to my car I found that someone had folded my driver side mirror in. Being a power mirror, I thought this was a bad thing to have happen. I didn’t seem to find all that much info on the web. The...

I have a 2013 Optima EX. I had to replace the little flexible coupling between the power steering motor and gearbox. Replacement went fine and took just over an hour. A couple days later I noticed that the ESC light was on constantly. I did forget to connect the brake light switch after the...

It's not even Black Friday yet, but Home Depot just dropped 10 killer combo deals on cordless power tools from Makita, DeWALT, Milwaukee, Ryobi, and others. Depending on the budle, if you buy one of their kits, you can get one or two bonus tools or batteries for free! Cordless impact drivers...

This may be a bit hard to explain, but I've noticed that my 2012 Optima (in great shape, no damage or collisions) takes more effort than it should to make minor corrections. It's easiest to notice if I'm moving at freeway speeds. If I'm on a freeway going straight and I need to make a very minor...

Hi, I am new to these forums and have some questions. I have a 13 Optima EX Turbo. I did a muffler delete on it about 2 months ago and changed the tips . I also installed the BOV sound plate from the K5 store. The car sounds very nice now. Sometimes I feel like the car doesn't accelerate as hard...

Hi, I have a 13 Optima EX Turbo. I did a muffler delete on it about 2 months ago. Sometimes I feel like the car doesn't accelerate as hard as it did before the delete. I did a lot of research online and some say you lose low end torque while others say you do not lose anything or gain anything...

Im looking to install a radio in the trunk of my 2014 Optima Hybrid. The radio requires a 12v all the time hot wire and ground. Easy enough for me to wire directly to the 12v battery for this. However I need to find a 12v power source that is powered by the ignition being powered on. Any advice...

Only works occasionally. Why?

This is on my 2013 SXL. I am hoping that someone might have an extra mirror that they had to replace due to damage other than this gear that wouldn't mind selling me this tiny gear, or even the entire assembly if need be. Mine cracked on one side and then spun over the spines of the metal part...

Today on the highway i went out to pass and felt a pop/hesitation then low power...off the highway i can now hear the turbo whine and have low power..i have replaced the wastegate actuator about 7k miles ago and know what that feels like..its not that....could i have lost a pipe or seal?

Hello, 2013 EX Turbo, 138k on it. Supreme gas and synthetic oil. I have had a few issues over the past few weeks with my 2013 EX Turbo. This has happened 4 times thus far. After the first time we took it to the dealer here in Fredericton,NB, Canada and after 200 bucks he could not find...

My 2018 EX has automatically folding side mirrors. I've had the car for a few weeks now and I noticed when the mirrors fold out, the driver's side makes a high-pitched squeak as it gets into place. It didn't do it before, so I'm hoping this is an easy fix with some kind of lube. Any...
