IAC restrictors and EGR restrictors

96greengt · 06-29-2007, 04:09 PM

I have recently made a whole slew of IAC restrictor gaskets and a few EGR restrictor gaskets...

Here's how they work:
The IAC restrictor takes the place of the stock IAC gasket, the inlet hole from the IAC to the upper plenum hole is massive. The new gasket has approximately a 1/4 inch hole. What this does is make your engine drop the RPM's faster then it would with the stock gasket. It does not decrease or increase performance and will not fix a high idle problem, but will reduce it some. Basically, when you rev the engine, the RPM's drop faster rather then hang for a bit and gradually come down. I just made 35 of these an hour ago, (I am bored at work, can't you tell).

The EGR restrictor is just the same more or less, but this actually will improve power to an extent. What it does is reduce the amount of HOT air going into the upper plenum from the EGR valve when it opens up. It does not hurt emissions or cause any driveability problems. I have both of these gaskets on my Mustang as of right now.
I have seen a guy selling these on E-Bay for just under 8 bucks shipped, well, I did what he did, but have a better price, and still using the same type material. I have limited supplies of the EGR restrictor as of now until I buy more materials.

These will fit the 4.6, 5.4, 5.0 and 5.8 engines, but the EGR gaskets benefit the modular more.

$3 bucks for a set of gaskets until I run out of the EGR gaskets.
I will ship these as a pair as well for the cost of a stamp and envelope.

no insufficient EGR flow codes? if not I want one of each. On the IAC, does it affect cold starts?

Come install and demo some for me Jody.

interested. pm me thanks

FYI, on a cold start, it may have a lower idle, but should be fine. I mean, how cold does it really get in Texas right?

Mine is AOK, no problemo.

No codes for me on either systems. The gasket for the IAC has the ability to open the hole larger for more air, more air = higher RPM. I set the hole toa 1/4 inch in diameter. The stock hole is 1/2 inch to 9/16 inch, depending on if it is OEM or after market.

Let me know either by PM or here who needs a set or individuals.....
