Review on 🔌 Autolite AP3923-4PK Platinum Spark Plug: High-Quality Pack of 4 by Chris Crawford

I don't know why Amazon thought these fit the Jetta 1.4TSI and this one doesn't (at least not my VIN). I've done a little research and it seems that there is some confusion between Jetta 1.8TSI and 1.4TSI spark plugs (possibly depending on VIN). Candles 1.4 have a significantly smaller thread diameter. I'm not sure if everyone knows about this. I suggest you test your spark plugs first, measure or check the model and then buy the right ones. I had to return them and buy original Bosch spark plugs (04E905612C) which are expensive but there are ways to get them cheaper on ebay. Much luck!
