Installed in a 2013 Hyundai Elantra GLS 1,8L engine. leery of counterfeits, I contacted NGK technical support and they had me send photos of critical areas of the plugs to verify authenticity. They assured me that these were the real deal. Been in the engine for 5 to 6 months now and no issues.

NGK is quality. It is pre-gapped and ready to install on a 2015 Hyundai Elantra. The original ones were the same and had over 100K on them. These are working great.

Fast Delivery, pre gapped, and product as described. Excellent price for a set of 4 NGK Laser plugs. Very happy with the transaction and the product. Good fit, excellent plug quality, and these offer the OEM performance. OEM replacement plugs for my 2013 Kia Soul 2.0.

These plug’s required different tools and were slightly different from what I always use. Had to remove immediately because they seemed to cause rapid loss of fuel.I put my old plugs back in to save the day. Don’t stray from what you know to be good… you may find it’s not what you’d expect.
