Got my 2019 Civic 1.5T to 93k miles and sold it this fall. Great car. Probably had some oil dilution because dipstick level would creep up. No CVT problems (drain and fill were done at 45k & 90k). Replaced plugs at 90k as well and they looked good although there was a little oil in cylinder 3. Ran great, no codes, high quality oil changes every 5k.

Pros: Great car, high quality

Cons: oil dilution

Vehicle: Honda Civic

Mileage: 149669 km

At 85k I swapped to NGK Iridium Ix plugs on my 2019 civic with the 2.0na and I swear it added at least 20% response. Makes me wish I would have gotten it with a manual cause it would be so much more fun to drive around town. Also got a few more MPG

Pros: added response, more MPG

Vehicle: Honda Civic

Mileage: 136794 km

I have a 2012 Civic LX (purchased new) and replaced the original spark plugs at 100k miles with **Denso 3483 (DXU22HCR-D11S)**—which were listed as compatible on RockAuto at the time. I’ve had great results and am now at 200k miles, looking to replace them with the same.

Pros: great results

Vehicle: Honda Civic

Mileage: 100000 km

Part number: 3483 (DXU22HCR-D11S)

Mi primer carro también fue un honda Civic 2005, lo tuve como 10 años, esos carros son fieles. Mi recomendación, primero hacele servicio mayor, lo podes llevar a una aceitera y que te cambien el aceite del motor, de la caja, ellos te ponen un sticker para saber cuándo hacer el próximo cambio de aceite, normalmente son como 2500 millas, cámbiale su filtro de aceite, de aire de motor, de aire de la cabina, las bujías, con las bujías el mío corría mejor con las ngk que con las Bosch que suelen poner en todos lados.

Pros: corría mejor con NGK

Cons: Bosch no tan buenas

Vehicle: Honda Civic

my 570+whp civic buddy terry couldnt get past 574whp... the plugs he was running, bkr7e race plug, had alittle brown speckle and melted the number 3 plug. after letting the car cool down for 30 mins or so, instead of retarding timing to run more boost he slaped in a set of ngk r5672a-9 plugs... and upped the boost 2psi from 27psi to 29psi... and BAM!!!!! 616whp.

Pros: increased horsepower, more boost

Cons: melted previous plug

I’ve had almost all of them destroy themselves recently.

A few months ago i had a intermittent misfire appear and went to investigate it but when I popped the hood while it was running, the wire on cyl 3 was literally popping and sucking itself in and out with the spark plug core still on. I took the plug out and the ceramic was moving in and out from the threaded bit. So it was gapping and slamming itself together while running.

I changed the one spark plug cause I had a spare ngk, I forgot about changing the rest and now I have a new misfire….. I can now feel the tick from combustion going thru the wires on cyl 1 and 4. So now 2 spark plugs are starting to do the same thing. I will be changing to ngk plugs now and won’t be touching Bosch.

Cons: destroy themselves, intermittent misfire, ceramic moving, popping/ticking

Vehicle: Honda Civic
