Thread: thrasher intake system

My car did that (although not as loud) with its stock intake...

any cold air intake does that noise on cold start up....... its not just thrasher.

Normal issue... Mine was kinda annoying too until it warmed up... It sounds like the vacuum at the car wash...

I had a thrasher on my GTP, and I loved it. Including the noise. I had proven results on my friends scanner with that intake. And I just purchased another one for my Impy.

After driving around in rush hour traffic for nearly an hour, I've done a personal check. Feel the aluminum box and it's rather hot from the air being blow on it from the radiator. Popped the lid off and felt the filter and the inside of the insulation... felt about ambient temp or just a hair over.

Good enough for me. It's the same stuff used in home construction, so it works well.

The intake tubing was even fairly cool inside when the outside was warm to the touch.

I do have one official gripe. If you mod a lot the intake tube will have to be replaced eventually. I've taken it off nearly a dozen times and the throttle body end is fraying just a little. It'll probably still go for quite a while, but worth noting.

ZZP does sell replacement ducts, or you can use your own. Up to you.

the tubing on the wiziar....eghhh. i went to auto zone and got some better tubing. i also routed the filter closer to the headlight and pushed the box up against the frame as much as i can, it had small gaps. now im just working on something to insulate the box even more to make it fully effective. the tubing can easily be replaced tho. pretty much your buying the box..

what about the cold air induction box??? it looked to be built VERY well. the wiziar for one doesnet even seal where the tubing goes into the box. its just got some flaps and hopefully that is enough. its a good design in general but it could use some modifications.

When I had my Thrasher, I always kinda dug when you shut the engine off, you could almost hear a gurgle from the filter. Almost as if it was human trying to get its last breath of air

But like everyone else, its common, no matter what size filter you put in it. You are still gonna get that sound. If you dont like it, which I can't see how (but to each their own) you could always switch back to your stock airbox or something more sealed to prevent any intrusive air noise *shrugs*

I just didnt like mine for the simple fact it could not keep the air cooled that sucked into the Thrasher. Reptile and I did a test one time after I covered the whole Thrasher unit in thermal wrap and the ambient temps were still way above board. The Wizair or even the MSP or an SLP unit unit would more than likely keep the air temps close to ambient.
