Will Aftermarket Headers Void My Warranty?
A warrant is an agreement between the car owner and the company that built the vehicle. It allows the company to take care of any repairs provided the owner maintains the car according to the required expectations.
So, will aftermarket headers void my warranty? No. But if the dealer proves that the aftermarket header is responsible for repair needs, they can deny you the warranty coverage.
Be sure to install the aftermarket header without causing more problems. If the cause of the part failure is unclear, the dealer will have to charge you a fee to diagnose the vehicle. But if the aftermarket part has nothing to do with the problem, the diagnosis fee will be refunded.
You should note that aftermarket parts usually raise a red flag when the car is brought for the service. Research more on car modifications and find a dealer who is a little more mod-friendly before making any changes.
Do Changing Headers Void Warranty?
We all have the desire to improve engine performance. High engine performance fosters a better driving experience regardless of the road condition. The addition of headers enhances proper air intake and exit from the engine.
So, do changing headers void the warranty? Yes. Any modification made on the car has a high chance of rendering the warranty void. But the dealer has to show that the changes cause the failure before denying you the warranty. A car brought for service with new headers will raise a red flag to the dealer.
Most car dealers can use the changes as proof to deny any work on the engine. Do not modify the system unless you can afford to fix the problem without a warranty.
Always take time to research the car dealer before opting to change the headers. Some dealers are pretty cool about the modifications. But ensure the changes do not cause potential damages in the long run.
Will Long Tube Headers Void Warranty?
Some dealers usually take advantage of car owners by denying them warranty coverage in case of repairs. Always consider seeking service advisor assistance when denied warranty claim unfairly since warranties are open for interpretations. So, will long tube headers void the warranty?
Yes. Long tube headers involve complex modification tasks and increase the risk of tampering with engine performance. But the dealer will have to prove before denying you the warranty coverage. Long tube headers usually tune the engine to get rid of the check engine lights.
Besides that, it allows more air to flow out of the engine and reduces the performance of oxygen sensors. The issue will later set off your check engine light. The good news is that the power train warranty will remain intact after installing the long tube headers.
Remember to consult the dealer before making any changes to improve your car engine performance to avoid rendering the warranty void.
