GrimmSpeed StealthBox Cold Air Intake - Subaru 2015+ STI Red (060078)Red Stealthbox Air Intake Kit (060067) by GrimmSpeed. Inspiration for the StealthBox Intake came from internal discussions about what we wanted from an intake system for the 2015+ WRX. Of course performance is the highest priority, but at GrimmSpeed so much more than that goes into a product. We wanted an intake that purred quietly under normal driving circumstances, but would roar at wide open throttle. We wanted an intake that looked at home in the

Red Stealthbox Air Intake Kit (060067) by GrimmSpeed. Inspiration for the StealthBox Intake came from internal discussions about what we wanted from an intake system for the 2015+ WRX. Of course performance is the highest priority, but at GrimmSpeed so much more than that goes into a product. We wanted an intake that purred quietly under normal driving circumstances, but would roar at wide open throttle. We wanted an intake that looked at home in the well-sported 2015+ WRX engine bay instead of a shoebox stuffed into the fender area. From here, the SteathBox was born. We took the concept one step further and referenced the F-117 Nighthawk as inspiration for the stealthy look of the GrimmSpeed heat shield. It should come as no surprise that the performance it packs is equally unique.

Nice to know you have full protection
After a sever thunderstorm took out my cable modem, It was nice to be assured I had replacement coverage for it. Filing the claim was effortless and the process to return the item was no issue at all. My only concern is that the cable modem is a CRITICAL piece of equipment for any individual or business. A sense of urgency on the behalf of Asurion to recognize this and expedite the replacement process would have been appreciated. No technician repairs these modems. Always cheaper to replace, especially one that the failure was attributed to an electrical storm.

Will always get the warranty
Easy to do, they could not fix it and refunded my money via an amazon gift card.

Asurion is a good investment
Bought an expensive gaming router 46 months ago. Just stopped working, had 2 months left on my insurance, they couldn't fix it and gave me a refund. Bought a similar router with another 4 years if insurance with Asurion and I couldn't be happier. All this in 1 weeks time. They are great

Surprisingly great service!
Surprisingly great service. I just didn’t expect my claim to be handled so efficiently. Replaced the purchase price of my printer that was 3 years into a 4 year protection plan.

Works, but reimbursement for damaged items come via Amazon Gift Card, not Cash
Just confirming that this protection plan actually works. Asurion first told me that they'd try and repair my item. Likely, they couldn't find someone to repair the type of item I bought (KVM), so they offered payment (original cost of the item) via Amazon Gift Card. Giving 4 out of 5 stars -> 4 instead of 5 because Amazon Gift Card isn't Cash. Cash is always better.
