Home-brewed bracket was installed to keep the horn from coming into contact with its surroundings. Notice that the filter-housing is actually not secured to the cresent-shaped bracket arm. This allows for some movement of the filter relative to the bracket when the engine rotates from acceleration and decelleration. Securing the filter firmly to the chasis could stress the silicone connectors and/or filter element. As an interim solution, I've applied elec tape to the (thin) aluminium horn and bracket (with a shot of lithium grease in between) in order to shield the aluminium horn from abrasion with the metal bracket. I'll probably end up buying a set of jam nuts so that I can secure the cresent shaped arm to the horn, and have it rotate freely about the bracket's verticle support. I was able to rotate the factory mounting point (which my bracket is bolted to) toward the front of the car for a better fit. IIRC, the bracket comes with HKS filters... it was left over from when I swapped out the HKS filter of the T04R kit (Supra) for another filter.
Detach the large hose from the hose-retention clip and re-route it to the otherside of the AC line. This will give the hose more slack. I've shielded it from the AC line with a piece of blue silicone.
Since the factory vacuum runner was bypassed, I capped off both ends in order to protect it... just in case I ever go back to stock... (yeah right).
Why doesn't the kit come with a bracket to support the horn? This is the second install I have seen with a custom bracket. Seems like that should be included.
I have the PRM on my car, install was very easy. Response improvement is defintely there, in spite of the various debates about it drawing in hot air. Sound is just what I was looking for. (And no real risk of sucking in a slug of water.)
I read several posts re: a support bracket, but after talking to the guy in Canada that sells them, I was convinced it was not needed. If properly installed, it should be fine without a bracket. They run them on race cars all the time with no brackets. Key is to rotate and align the pipe/filter/horn joints so that it clears everything. Loosen a little on one, adjust it, tighten it, play around with another joint, etc. No big deal, just takes a little time.
However.... I check mine every time I rasise the hood. 3 months and about 2,000 miles, no problems so far. Doesn't rub on anything and nothing loosening up.
