wbt, why did you mention the JLT products? They have been proven to perform, of course with the addition of a tune. I know the stock airbox is a damn good piece on these cars, but can you explain? I'm actually curious.
Sure that is easy.
1. Their CAI design on the 2011+ cars is flawed.
2. Their catch cans have issues with fittings breaking.
3. The company owner has such a large ego he refuses to admit when his products have issues yet he is willing to make video's about other vendors ripping him off.
....and much more going on behind the scenes that isn't as public. For me that says everything. If others are happy running his products that is their prerogative. That's my opinion.
