How do know they don't just buy from or work with eachother in order to sell more?
Because a respectable company that is a vendor for the other does not take credit for other peoples work, copy their website word for word, and even take the other companies logo and slightly modify it so it is similar, and then charge $6 a pair more. Those vents are RunCool Vents, which Troy runs on his SFA KJ, and I personally talked to the guys at RunCool and they generously donated a set of THEIR vents for the LOST jeep Safari in Ouray a few years back so the procedes could be donated to a good cause.
Here is RunCools Logo:

Rocky Roads

Then read RRO's site starting here: "Now, the world's first, universal-fit, pop-rivet-on, metal hood louvers-no need to remove, punch and repaint your hood..."
Then read the runcool site on the left column. And compare the Q&A section of the runcool to RRO.
Also take close note at the info posted underneath each of their louvers: "MADE IN THE U.S.A. -
PATENTED"
One time a long time ago I made the mistake of marketing a product under my company name as I had a "business relationship" as you are mentioning, and it came back to bite me in the @$$, so I will never take credit for another companies work again.
Support a credible company that has actually donated to the LOST community and are good guys to deal with.
Just my $0.02.
