Any opinions about these 2 spark plugs:
They are going to get installed in a Mitsubishi Lancer 4A91 engine that has been converted to LPG.
The price of the Bosch ones is about $9.30 per plug and NGKs are priced at $15 per plug.
Is there really any difference in their quality regarding their performance or their lifespan?
