Offering the SAIS/AIP Secondary Air Induction System Bypass Module and Block-off-Plates kit Georgia Dave was previously offering on his thread Ultimate AIP Bypass Model -new version available.


On September 31st, 2014 when Georgia Dave posted on his thread that he was getting out of the SAIS/AIP bypass business, my father and I teamed up to produce the same high quality Module that GeorgiaDave developed and produce himself. So this means you can still get the same exact bypass module kit!!


What we are offering is a very simple plug-and-play solution. It requires ZERO modification to your existing wiring! This means NO cutting wires, NO splicing, and NO soldering! It simply plugs in place right at the MAF (Mass Air Flow)sensor. If you’d ever find the need to remove it, well, it comes out as quickly as it goes in– a few seconds is all it takes to get the module in place. Complete instructions come with the kit.

Frequently asked questions about the SAIS/AIP Secondary Air Induction System.​


What is the SAIS/AIP Secondary Air Induction System?

The SAIS/AIP system pumps air into the exhaust on start up to help get the catalytic converters up to operating temperature faster and thus improve emissions. It does not have any affect on performance unless the system fails. Two modes of failure are common, the air induction pump fails or the exhaust valves get stuck open or closed causing your vehicle to go into limp mode.

What noticeable problems will I have with my SAIS/AIP Secondary Air Induction System?

Besides the codes that will occur with this system an obvious problem is you may hear a sound like a vacuum cleaner at the first minute or less of starting your vehicle. Note you won’t hear this sound if the valve(s) have failed. These sounds generally come from the pump vanes that are in the process of failing due to various heat and corrosion related issues.

When you turn on your ignition the computer will determine whether or not you've had a failure in one of the 2 air valves or the blower motors. The computer will then send an error code turning on your check engine light and specifying the failure mode.

What CEL (Check Engine Light) codes may appear if the SAIS/AIP Secondary Air Induction System is defective?

P1441 - Secondary Air Injection System Switching Valve No 2 Stuck Open Bank 1
P1442 - Secondary Air Injection System Switching Valve No 2 Stuck Closed Bank 1
P1444 - Secondary Air Injection System Switching Valve No 2 Stuck Open Bank 2
P1445 - Secondary Air Injection System Switching Valve No 2 Stuck Closed Bank 2
P2440 - Secondary Air Injection System Switching Valve Stuck Open Bank 1
P2441 - Secondary Air Injection System Switching Valve Stuck Closed Bank 1
P2442 - Secondary Air Injection System Switching Valve Stuck Open Bank 2
P2443 - Secondary Air Injection System Switching Valve Stuck Closed Bank 2
P2444 - Secondary Air Injection System Switching Pump Stuck ON Bank 1
P2445 - Secondary Air Injection System Switching Pump Stuck OFF Bank 1
P2446 - Secondary Air Injection System Switching Pump Stuck ON Bank 2
P2447 - Secondary Air Injection System Switching Pump Stuck OFF Bank 2


What are my options to fix the issues with my SAIS/AIP Secondary Air Induction System?

DYI method; plenty of information available on forums, some easy to find parts and materials, a good amount of wiring, and you’ll be on your way.

A bypass module that involves cutting and splicing into your existing wiring; takes some skills with a soldering iron, but has all the info and material you need to install, and is an easier avenue than the DIY option.

An easy plug-n-play bypass module that involves no cutting, splicing or soldering of your existing wiring; plugs into the harness connecting your MAF (Mass Air Flow) sensor to your ECM (Electronic Control Module).

All three above mentioned options are far less expensive than what your dealer will charge. Of course, anything that bypasses federally mandated emissions system can't be used on vehicles on public roads.

Frequently asked questions about the SAIS/AIP Secondary Air Induction System Plug-n-Play Bypass Module and Block-off Plates, No Cutting Wires!!!!


Is the SAIS/AIP Secondary Air Induction System Bypass Module easy to install?

Yes, this module was designed with ease in mind, this module will eliminate the need for cutting or modification of your existing vehicle wiring – it simply plugs into the wiring harness connecting your MAF (Mass Air Flow) sensor to your ECM (Electronic Control Module).

Are the Block-off-Plates necessary?

The block-off-plates should only be used in conjunction with a SAIS/AIP bypass module. Two plates are required for your engine. Note that the 4.7L plates differ from the 5.7L plates – you must have the correct plates for your application!

The SAIS/AIP Secondary Air Induction System includes air tubes that connect to the rear of the exhaust manifolds on each side of the engine. The block-off plates fit in between this connection to stop exhaust gasses from backing up into the SAS/AIP system when used with a bypass module. The block-off plates prevent exhaust gasses from leaking back into the SAIS/AIP valves.

For codes P1441, P1444, P2440, P2442, you ‘must’ install the exhaust block-off plates. We highly recommend installation of the block-off-plates in all circumstances, but for these 4 codes, the bypass module and the block-off-plates are required to prevent these codes.

What happens if I leave the key/Ignition on more than 10 sec without starting the truck/SUV?

The only requirement imposed when using the bypass module is that you must start your engine within 10 seconds of turning the ignition key to the ‘on’ position. The module works by bypassing the thermocouple in the MAF (Mass Air Flow) sensor during the initial 10 seconds of the ignition key being turned to the on position.

If you turn on the ignition, and fail to start the engine within 10 seconds, simply turn the ignition key to the off position for at least 1 second before attempting to start the engine again.

Can I pass an Emissions/Smog test with the SAIS/AIP Secondary Air Induction System Bypass Module and Block-off-Plates installed on my truck/SUV?

Our product is designed for off-road and/or racing use, or for vehicles otherwise exempt from vehicle emission laws. Modification of your emission controls may violate federal, state, and/or local laws. If you decide to purchase our kit, you assume all risks associated with its use, and agree to hold the maker harmless from any claims of damage, loss, injury and/or legal consequences due to installation of this product.

Off-road and performance exhaust systems generally do not have the necessary port for connection of the SAIS/AIP system - for these systems, the SAIS/AIP Bypass Module is a must to prevent your engine from going into 'limp' mode.

Hi, does this affect the amount of clean air reaching the catalytic convertor which might cause them to prematurely fail? If the air pump isn't pushing air to the catalytic converter, do you have an electronic solution to disconnect the catalytic convertors and not get a check engine light?

Hello everyone,
Anyone know for sure if the pump fan still activates after installing this bypass? I'm curious to know if a pump is screaming when going bad if this shuts the darn thing up? I've read the bypass does stop pump fan from running and I've read it won't, guess it depends on design on things idk, thanks?
