blonkers
A form of eyewear. 

Similar to blinkers and totally invisible, blonkers are usually worn by car enthusiasts loyal to one particular car manufacturer and model. Not always easy to spot being worn until the wearer starts telling you how much their car weighs, it's power to weight ratio etc. A dead giveaway would be if they tell you how difficult it is to properly tune an NA engine.  
"Dude, Honda built the Integra Type-R DC2 as a stripped out road going racer"

"Oh ffs, check out the blonkers on that guy....."
