Autolite Iridium XP Automotive Spark Plugs - XP5703 (4 Pack) - High Performance Replacement for Smooth Engine Acceleration & Fuel Efficiency - Ideal for Cars, Trucks & SUVs

Worked absolutely great. Went in and changed all four spark plugs. Found out in the end it was the ignition coil on cylinder two. But the plugs needed changing. I was at around 93,000 miles so it needed it. Also changed that ignition coil, then the pcv valve, and both engine and cabin air filters. Definitely recommend hasn’t done me wrong yet.Fast shipping and fits my Veloster Turbo 2013, thank you!Put in my 2015 Sonata 2.0turbo without any fitment or operation issues. Replace for the recommended 45k service, no issues so far.Great product have used them before, after job complete vehicle had misfire cyl #1. Bad plug had to see local vender to complete tune up, brand new spark plug. Otherwise great productIt’s goodThis fits my 2015 Kia Optima Hybrid LX 2.4L HEVThese spark plugs DONOT fit for a Hyundai Elantra. The sparks in them have cause so many error codes on my vehicle because of them. And they are not sized for .044 which is suppose to be for a hyundai elantra 2012. These spark plugs almost fried my motor. NEVER AGAIN.I am not comfortable to install these plus to my Sonata . I looked at these plugs closely and found 3 out of the 4 tips are not lining up to the center , some toward to left some toward to the right. ( See pictures) And when I measured the gaps ,one of them been closer then the others. I Don't have the confidence to install them and undo it later. I will return them and get other brand.I've been looking FOREVER for a set of four 3479's that didnt' cost almost $100CDN+. You just can NOT get them. I just happened to find these, price was perfect, arrived in days. no more power loss @4000rpm, cyl2 plug was finished**Fits KIA/Hyundai Theta 2 (Turbo GDI) for Denso 3479 replacements exactly!**Less then a year and 30,000km 2 of 4 plugs replaced were defective. Found out when car started running rough and eventually caused a misfire in cylinder 2,3. Stick with OEM partsThese are a perfect fit for my 2013 Veloster. The car feels like new after installing them. It accelerates much better and feels like the power has also been restored. And the price that cannot be beaten! Very happy!Fits 2013 Hyundai santa fe 2.0l turbo perfectly. Works as it should.After 6 months my car started misfiring again!! I do not recommend they don’t last that much I have a VT
