These units facilitate easy installation and are backed by a limited lifetime warranty.

This company offers profesional service at a very competitive price. The header collectors i ordered were not available at the big speed outlets. The fast shipping was also a plus. I would recomend Autoplicity to anyone who needs parts in a hurry !
