Spark plug Bosch or NGK

I had those on my 2017 civic 1.5t sedan that I had some performance mods done to and they worked great

I change spark plugs - I change my plugs every 30,000 miles spend the extra money for NGK.

Only ever buy ngk plugs and learn to read their reference chart then you will always know what plugs you can/can't use for small engines

Personally I gapped my NGK laser iridiums to .024 and I've had no issues what so over, I did however have issues with the OEM spark plugs when I pulled them out to which they were gapped at .054, which OEM spec is technically .034

I swear by NGK

Apart from that, NGK is my go-to brand for everything they make.

I am running LiquiMoly Molygen at the moment, use LiquiMoly Engine Flush and Direct Injection Cleaner when chaining oil, put in new Bosch plugs and coil packs about 9 months ago.

Used those for the same setup with no drama, stock gap measured at 0.026". I've run lots of different plugs....honestly, they make zero ****ing difference IMHO on my peasant IS20 and 38 1.8 sLOw OTS Uni tune...

Well, shit. I just put new plugs in two months ago following what EQT recommended then! I didn’t know of these failures with projected tipped plugs. Guess I should have spent a little more and bought non projected at the time, dammit.

Although I prefer Bosch sensors over other brands in certain parts of my Mk 5 2.5, I will not buy Bosch spark plugs. Many professional mechanics over the last 3 decades have told me horror stories about them.
