My right muffler fell of due to rust, got a whole stock rust free catback for free. that shit is heavy, i'll be buying corksport or similar soon, time to loose the weight on the Targa piggy, also taking the Aluminum TII hood off my '91 that'll qualify as a very nice free mod as i will be selling the extra car.

The part that says 13B MAZDA, or even better, further down the manifold. It's hot. Think it through, even with a nifty cold air box your air will always encounter the hot metal manifold that any unmodded 7 will. I dare you to leave your hand on the lower intake manifold for more than 10 seconds. It's very hot and think of your "cold" air passing through there. Air intake does not stop at the filter!
Now, ask yourself- is there really any such thing as a "cold air box?" I'm waiting for someone to invent the cold air manifold!

You should go try it, I think you will find its cooler than you think.

I also forgot to mention that the way I mounted the rubber bands was just one at each corner, so four in total. Each was wrapped around the bulges where the nuts were a few times nice and tight.
NOTE: I should remind everyone, check on the rubber bands every now and then! In the first week I had them on, one came off. But since then, I havn't had any trouble with them and they still maintain thier elasticity.
Hope I solved most of your questions :) .


If I didnt have a cone now i would totally steal your idea with the rubber bands,.. i wonder why i didnt think of that instead of duct tape lol.

P.S just take the top off, leave the snorkel there so you still get some fresh air.

Huh?... Do you mean the top of the air box and leave the snorkel? Because that's exactly what I did.
By the way, in regards to the other post above, I know for a fact that the intake manifold generates ALOT of heat. One night my accelerator cabel got stuck on the cruise control thingy and I had to repair it in a parking lot... with no light. It sucked, I advise anyone who doesn't believe me to try it themselves. Also, once again, like I said before, I was looking at a 7 for sale this past weeked that had a metal tube attatched from the cone shaped air filter to the manifold and the heat was such that it was burning a hole in the heat shield under the hood.

CHEAPEST MOD EVER: I raced a taurus (not SHO) and lost, so i did a compression test. I found that the spark plugs easily unscrewed by hand. I was losing compression through the spark plug holes! I raced him later that day and walked him. (The first race was before school, the second one was after school. I can only imagine what was going through his mind)

kinda late but..... whats funny is that that rubberband thing actually worked. I exposed the filter and held it down by rubberband increasing flow. I can actually feel the difference. :O) weird and cheap

Lol, I thought I remembered reading something about this before I did it. Good job. I think it makes a difference, but no dyno results to prove it...... Yet.
