This was an unknown seller to me & I was pleased with the buying experience.

Worth it for sure! I was so happy when I installed it

Pretty fast shipping. Even faster if you order during the week...at least ime Excellent customer service. David is the man switched up and order at the last minute on a throttle body spacer. Will order all my parts from the kia/optima store.

Love it! Looks alot better than the old Kia logo.

Shipping was quick and service is great

Super amazing. Really nice drop, handles amazingly better than stock. Highly recommend if you’re not going for coils- rides just as well as stick with a little bounce that makes it fun :)

Super fast shipping!

Fast trouble free shipping and fantastic parts as always.
