Hello, just purchased a 2018 Sport DCT I love this car so far. My other car is a 9TH gen Civic Coupe with a custom turbo kit. So I had to get another turbo car. Already have mods on the way. I did notice the car had a slight misfire while cold so I ordered some NGK coil packs along with New air filter, and Updated Bosch Spark Plugs. I hope this will smooth out my cold starts.

Only 17k miles. Kinda weird to be having coil pack issues, but after looking into issues with 1.6T it looks like coil packs fail often.

Known issue with these motors regarding the coils. I got msd blaster coils which resolved the issue with the stock plugs, here's hoping the ngk ones resolve it for you as well. Congrats and enjoy

So warranty will not replace them? Like said it is a common issue along with
EBCS failures.

Did you notice any performance gains? The car feels like it's struggling past 80MPH so I don't think I've felt the full power of the 1.6T yet. I went with NGK because after using OE Replacement coils on my Civic they failed within 3 months. DENSO claims the new double Irradium tips to use 24% less energy to ignite.

Didn't know they covered the replacement at the dealer. So I will be calling them tomorrow. Thank you. If they do replace them I'll sell them on here for some poor soul who went over on their warranty time for a really good price. I just got my NGK coils.

Delear told me they use Delphi coils on all repairs. Those coils are on backorder. I don't like other people working on my car anyway.

Trying out the stock plugs gapped at 0.028. I checked the gap two were at 0.028 while the others were at 0.32 might have been why I had issues.

Yes even though they are supposed to be pre-gapped you should always check them. May have found your issue too.

100% better now keeping stock plugs since they are NGKs. 0.028 is the best gap I now even have burbles on decel. What an awesome car! Trans even shifts smoother now! I guess it all makes sense if you're not making the proper torque the computer and clutches can't compensate for the power.

NGK coils, Wix air filter, and Proper spark plug gapping have gained 12mpg. I was averaging 25mpg before. Also I had the wrong oil put in by car max. 5w40 conventional. I guess it's still within spec, but why have that thick of oil in a stock engine. I now have Valvoine Full Synthetic 5w30. Also removed the air box and cleaned out all the debris so that might have helped as well. Also ran two cans of Liquimoly fuel system cleaner. I only fill up with Shell 93 for the last 5 tanks. I can really feel and hear the turbo spool.

A tech bulletin came out some time ago addressing the fuel dilution problem DI motors have. The higher weight oil is supposed to help mitigate this problem. I have changed to 5w-40 synthetic and will change oil at 5K intervals.

I will have an oil analysis done at 3k miles. I change my oil every 3k miles on all my cars despite what dealers say. Honda recommended 0w20 on my 2012 civic. I drove home and drained that right away. Been running 5w30 for 83k miles. 20k being boosted @ 14psi 350whp. After filling out a questionnaire on hyundai.com they said with my driving conditions 3k is recommended. 5w30 has done wonders on my civic, and I take it to 7,400rpm every time I have it out.

I think the main thing with a turbo car especially is you run synthetic. Ran 10W-30 (factory fill) in my Evo for years. Was tuned for E85 and made 450whp @ 28 psi. Had my oil checked @ Blackstone and got good reports
even with occasional track use. They said my oil looked good at 4K and could possibly go more. They too back then recommended a 5W-40 oil due to ethanol use. That was a port injected car and fuel dilution wasn't as big a problem.

I called car max right when I felt the miss fire at cold start. When they told me they put 5w40 conventional. I knew right then that's why the car felt so sluggish. You're right a full synthetic is a must on a turbo car. Anyone who says another wise I wouldn't even let them check my tire pressure for me lol. I maybe be a little overkill at 3k, but ill see what they say for the little 1.6T soon.

Also car max got so mad when I told them off for putting conventional oil in my Turbo car. All the service techs looked about 13 years old. Not a single hair on their chest. Never get service there FYI to all you turbo guys!

I have known to avoid Carmax after hearing from my son who was a mechanic apprentice there. He quickly moved on. Using the new API SP rated oils is supposed to help with LSPI issues the DI turbo cars are seeing.
"The new standards specify more stringent engine oil performance requirements for spark-ignited internal combustion engines. The three include seven new tests, including a chain wear test and a new test for very low-viscosity engine oils. The standards also include a test designed to protect against a phenomenon experienced by some gasoline engines known low speed pre-ignition (LSPI). "

5w40 is always synthetic. Its what I run in this engine.

Glad he knew better. I will never bring my car into another Carmax.

I will try out 5w40 next oil change.

Spent the day waxing this beauty. The only thing left is some window tint and better tries. Plan on keeping this car mostly stock.
