OEM Honda › Spark plug

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

On my Honda Fit that would be an excellent price because you have to take off a cowl to get to the plugs.

Pros: excellent price

Cons: cowl removal required

Vehicle: Honda Fit

39 dollars for parts? Hopefully they aren't champion plugs. Hell of a deal

The most expensive proposition was a new windshield, but your particular insurance could solve that. Spark plug replacement was a surprise as far as cost is concerned. I've routinely changed the oil and cvt fluid once. No other maintenance issues. I love the car. Incredible roominess in the cabin and very capable offroad when needed.

Pros: no other maintenance issues, capable offroad

Cons: expensive windshield, costly spark plug replacement

Vehicle: Subaru Forester

Mileage: 98000 km

When I started the vehicle up, it woke up really aggressive, there was a strong gas smell and it stuttered badly when driving her, along with the check engine light flashing at me when I did the test drive.\n\nAfter taking out the coil pack, I found that there was a lot of crap inside the springs within the boots...looked like dielectric grease gummed up by the previous owner. After cleaning all those springs and making sure they were straight, I took the new Spark plugs out (Champion Copper) I rechecked the gap and they were all good, after putting everything back together the old girl started up quick as hell, no shaking or anything. I drove it for 15 minutes and I had no issues whatsoever.

Pros: started up quick as hell, no shaking

Cons: strong gas smell, stuttered badly

I stopped buying plugs from eBay and Amazon years ago after getting what I can only assume was a bunk set for my BMW. They looked the part, but caused the engine to run rough.

Pros: looked the part

Cons: engine run rough

Vehicle: BMW

I stopped buying “NGK Iridium” plugs on eBay AND Amazon a while back. They’re nearly all chinesium knockoffs.

Cons: chinesium knockoffs
