Just to let you know about Steeda ... we have had 0 issues when our tune and CAI have been directly installed on a consumer's car.
Secondly, just because you install and aftermarket part on your car does not automatically mean the warranty is voided. In order for a warranty denial to take place, Ford would have to do an investigation to prove that the aftermarket part indeed caused the failure. Steeda would be in fact with you the whole way. Just remember no warranty covers abuse.
We work with Ford Motor Company and SCT to ensure that our tunes are top notch from the begining ... we stand behind our products 100% and if there were ever an issue with one of our products then we would go to bat for you ...
Yes ... our warranty is the fact we stand behind our products ... without a warranty ... you would think we would be in a risky situation ... but knowing these cars inside and out we find no reason to put a "limited" warranty on a product that we know won't cause an issue.
Our CAI is American Made right here by the American work in our facility in Georgia ... We are an ISO 9001:2008 certified company which means we are held to very strict standards.

We will update your tune when you purchase a part directly from us ... if you need revisions done to the tune then we will do those for free.
Since you are buying your parts at one ... one tune in the begining should take care of most of your tuning needs ... unless you were to upgrade to another part that would cause a tune revision in the near future.
We stand by our numbers and our history ... you can do a search for Steeda tunes and see how many failures they have caused vs. the competition ... but I will save you the time since 0 will come up for Steeda.
Also, Steeda races what they sell. You won't see to many other companies out on the race track every weekend like Steeda. We have a rich history and we feel it translates into our parts.
Best Regards,
TJ
