★ IMPORTANT!! BEWARE of PHONY ATTACK BLUE FILTERS FOR SALE!
Sorry for the long post, but this needs to be said—
We’ve been made aware of multiple “companies” selling fake C7 & C8 Corvette Attack Blue filters across Amazon, eBay, and other online retailers (one example: “Friday Parts”).
This is not just a trademark issue—it’s a quality and safety concern. These are NOT our products. They are not made with our materials, standards, or testing. Quite simply, no one knows what filtration media is being used in these knockoffs.
Some listings are illegally using the names “Attack Blue,” “Attack,” or “Blue Attack.” Others are using our product images, test data, descriptions, and even part numbers. We’re also seeing listings claiming “Made in the USA” while shipping from China.
If a seller is willing to lie, steal content, and misuse our trademark, ask yourself—what exactly are you putting in your vehicle?
We can say with 100% certainty: these are NOT genuine Attack Blue dry nanofiber filters made in the USA.
We are actively working to address this. In the meantime, please purchase only from trusted sources.
Authorized sellers:
Amazon: West Coast Corvettes/Camaro, SR1 Performance
eBay: West Coast Corvettes/Camaro, SR1 Performance, Corvette-Guys, Mid America Motorworks, Corvette Central GS Creations
For all other purchases, please refer to the authorized dealer list on our website.

UPDATE:
So with the help of an attorney, we were able to have some (not all) of the people selling filters using the Attack Blue name and Attack Blue pictures, removed. We are slowly having them all removed. Unfortunately like roaches, you kill one, two more show up. So its a process.
Shame we have to spend good money because of bad people to protect what's legally ours.
If you are looking for Attack Blue filters and you buy on Amazon, SR1 Performance & West coast Corvette & Camaro are legit. Easy to spot. Thay have over 140 positive reviews and has "Made in the USA" in the title.
Thank you

Does it say "Attack Blue" on the filter? If not, it's a fake.
We have no idea what their filtration media is, if its actual nanofiber, and how well it filtrates. Just that its dyed blue. Some of these enema bags are posting our actual data graphs we made a while back as their own!
Is it washable? No clue. From what I heard most don't even come with instructions.
For every fake one our attorney gets pulled from Amazon, 2 more fake ones pop up. They are either straight up using our pictures, the name "Attack Blue" in the title (and the description) or just the word "Attack" which will also help bring it up in a search and create deception.
The only 2 legit company's I know selling on Amazon are West Coast Corvette/Camaro and SR1 Performance.
Feel free to contact me, as I can go over your situation in more detail. 800 778 9898

I put the OEM filter in the attack blue box and I looked at the box just now. It has 2 stickers. One is printed with Air Filter 41100010 and the other with Air Filter 4100...Stingray Attack Z51 LT2 and on a second line X004MH0689 Made in China.

I don't remember if it had Attack Blue on it. I would have to remove it from the car to see.

That is not a Dry nanofiber Attack Blue filter.
The name on the box ."Stingray Attack Z51 LT2" Was used to help deceive people thinking it was an Attack Blue. Apparently, it worked.
"Made in China", also another dead giveaway.
Attack blue is 100% made in the USA.

I went ahead and ordered one from West Coast Corvettes / Camaro through Amazon. My car is too special to me to screw around with a knock off air filter. I hope it gives me that 11hp so that I can say my Z51 has 506hp instead of 495hp 
Thanks for the education Ed.
I received the original Attack Blue filter last week and sure enough it is embossed with Attack Blue right in the plastic housing. The filter material in the knock off and this one looks similar but then who knows. I feel better knowing I have the one that has been dyno tested and is the original maker.

West Coast is a great vendor. In all actuality all of the legit distributors are fantastic. It's the overseas scum that ruins it.

why?... I don't know? lol
You can obviously buy trough us or directly on the Attack Blue Filters website. But sometimes other (our distributors) have sales, better deals so we encourage people to check it out & take advantage of that. Others just like to deal with a specific company. Possibly because they have delt with them forever.
So, in any case, we are good with wherever its best for you. But regardless of where you purchase your Attack Blue Filter, if you ever have any questions, please do not hesitate to contact us directly.
Thank you!

Theses "companies" are still using some actual "Attack Blue pictures" and some are using Attack Blue data sheets as their own testing. (its unbelievable).
So once again, Sorry, just trying to get the word out.
