About Us  

UK born and bred, Boost Kings originated from the desire to not only make modifying vehicles cheaper but for those mods to remain effective and without compromise.

We source from a selection of manufacturers to keep costs low and quality high. Often we find quality can vary from manufacturer even if the part looks the same, so we personally find the best ones, which is often more expensive from some of the budget kit available. Performance over profit.

We try to respond to emails and questions within 24-48 hours and generally will do between 10am-1pm most days aside from holidays/weekends/show days etc.

Please have anything your purchase from us installed professionally by a licensed specialist/garage etc. We hold no responsibility for any damage to your vehicle or any running issues encountered by installing aftermarket products.

Please drop us a message if you have any questions or simply need a little advice about our products and please read our terms and conditions below before purchase.

Thanks for choosing Boost Kings!
