Its too bad that happened. I can understand your frustration and agree the filters were not labeled very well.
I ordered those before by mistake. Actually not my mistake as they were incorrectly described on the website but I suspected that because the price was cheaper than I had seen elsewhere.
Now I buy 2 sets of those for every set of the inner and swap the outers which gives me some more runtime on the inner before needing to be replaced. The Power Save filters are the best Ive used. When you have it set correctly they really do fit extremely well and the foam is nice and dense. I would still seriously consider using them.
I hope your engine is still runable and that you can find a new job. I see you live near Baltimore. I hope to make it up to some races at Nuclear which isnt too far away from there. I live in Bowie and have been doing nitro for some time if you need help with anything send me an email
