They make several sizes so I can get them inside of two weeks. I need three measurements. The two ends (filter, not throat) and the length (filter, not throat).
Just some info-
I sell the dycharger which is water repellant. Click on the link I posted. It's a very short vid showing the feature. This is my truck being tested. I have a semi functional hood scoop with dreams of it being a totally sealed system- all air comes in through the scoop. The drycharger was my missing link to doing this. I went three months without going through a car wash.lol. I now have the confidence to do it.
Second- What first amazed me with it is when I started the engine, the drycharger did not "suck up" to the filter. It covers the whole filter, all air has to pass through it, yet it didn't suck into it. That's the best way I can describe questions about it possibly restricting the air flow.
Third- the reason you are probably asking about it. It looks good. You can put it on when you want to show your truck. You can take it off when you want to show the truck because the main filter stays clean. You can go either way.
