Exceptional Service from High On Boost!
I ordered a set of NGK Laser Iridium spark plugs, but the package arrived with only 3 instead of 4. I messaged High On Boost on Instagram, and they responded immediately—no excuses, no delays. They shipped the missing plug the same day, free of charge, and I received it the next day.
Their urgency, professionalism, and customer-first attitude really impressed me. It’s rare to see this level of service, especially in the car parts space. Genuinely so happy with how they handled it. Will definitely be buying from them again.
👍👍
Arrived quickly and provided 10% off, first time using will be using again
Perfect in every way I couldn't be any happier will definitely order again,even got a hand written note lovely touch.
