Great service x2

Spark plugs are spark plugs (pre gapped is nice)… if your tune requires it then get them. As for N75, they have great costumer service I recommend buying anything for them. I have had several questions about my Veloster and the tune Dan has gotten back to me same day, every time and with the info I wanted not just “I’ll get back to you”. Installing the plugs and getting the tune next month can’t wait. N75 has made it a great experience.

Great service

I bought some spark plugs from N75 and everything was great. The spark plugs were in great condition, and came pre-gapped to what I needed. They let me get the spark plugs custom gapped for free, they shipped the product out very quick, threw in a N75 sticker, and even threw in some candy! Those candies earned you guys a returning customer. Me and my buddy were super pumped as we were literally just about to go up to the store for candy, but N75 already had us covered!

Great Performance Plugs

I had installed these plugs right when I got my first tune, and everything runs smooth with zero issues. Plugs are pre gapped to Hyundai spec so very simple install, completed in less than 10 mins.

Great Plugs

Swapped these in when I installed my Scorcher on my Elantra GT N-Line. No problems, work great, no knock.
