>> What is a throttle body spacer???

A Throttle Body Spacer is an add on to your air/fuel intake area. Originally used in the days of vehicles with carburetors, a throttle body spacer would allow additional fuel/air mix to be present to allow for additional power, or was used to "disturb" the air in such a way so that the fuel would form smaller droplets. In current fuel injected vehicles, the throttle body spacer allows for a greater and more forceful amount of air so that your engine will not have to work as hard in getting the air into the engine. >> Back to top

>> What types of gains can I expect from a throttle body spacer???

Although performance levels will vary among different applications and driving styles you can expect the following gains with the use of a throttle body spacer: Up to 18 HP gains Up to 4 miles per gallon gains Up to 25 ft lb gain in torque >> Back to top

>> Is a throttle body spacer difficult to install???

Throttle body spacers are generally quite easy to install. Most of them can be installed within 30 - 45 minutes with common hand tools. If you purchase throttle body spacers which are manufactured by reputable companies you will get a complete kit, including all hardware and gaskets making installation that much easier. >> Back to top

>> How does a throttle body spacer work???

The throttle body spacer adds velocity by effectively improving the vacuum response to the TBI or carburetor. The throttle body spacer, effectively increases the runner length of the intake manifold while at the same time increasing the overall plenum volume. This, in turn, also acts to prevent any of the air-fuel mixture from hitting the bottom of the intake manifold and bouncing back up to scatter in the intake manifold increasing overall performance and throttle response. >> Back to top

>> Are throttle body spacers street legal???

If you purchase throttle body spacers which are manufactured by reputable companies they are guaranteed to be street leagal in all 50 states and are 100% C.A.R.B approved. >> Back to top

>> Will the use of a throttle body spacer void my factory warranty???

The use of a throttle body spacer will not void your factory warranty. Specialty Equipment Market Association (SEMA) is an automotive aftermarket association that represents the industry in many matters. It's especially an important body in legislative matters and as such functions as a major lobby to state and federal legislative bodies in America. According to The Consumer's Bill of Rights of Specialty Equipment Market Association (SEMA): Article 1: You have the Right to buy high-quality reliable aftermarket performance and specialty parts, accessories, and styling options. Article 2: You have the Right to use high-quality aftermarket parts and know that your new vehicle warranty claims will be honored. In fact, your vehicle dealer may not reject a warranty claim simply because an aftermarket product is present. A warranty denial under such circumstances may be proper only if an aftermarket part caused the failure being claimed. Article 3: You have the Right to install and use emissions-legal aftermarket performance parts without incurring hassles and onerous procedures during state vehicle emissions inspections. Article 4: You have the Right to actively oppose any proposed (or existing) laws or regulations that will reduce your freedom to use aftermarket automotive parts and service or will curtail your ability to take part in the automotive hobbies of your choice. Article 5: You have the Right to patronize independent retail stores and shops for vehicle parts and service. The U.S. aftermarket offers the world's finest selection of performance and specialty parts, accessories, and styling options. These aftermarket products satisfy the most discriminating customers seeking personalized vehicles for today's lifestyle. >> Back to top

>> Can I use a throttle body spacer with my aftermarket cold air intake???

It depends upon the type of throttle body spacer, the type of cold air intake and the type of vehicle. Your best bet is to purchase your throttle body spacer from the same company that manufactured your cold air intake. >> Back to top

>> Does the Helix Power Tower really work???

Since 1997, Taylor Cable Products spent thousands of dollars in research &development, data acquisition equipment, and thousands of man hours to produce a product that the general public can purchase, install and enjoy. Using simple properties of internal combustion engines, if you supply more air and fuel into the combustion chamber, you can produce more power. Installation of the Helix Power Tower induces more air into the engine (5-8%), the fuel injection senses this presence and increases the fuel delivery. In turn, the extra power gained will let your foot ease from the accelerator. Up goes the fuel economy. The secret is torque. The more torque delivered to the wheels the better the throttle response, the better the power, and better fuel economy. >> Back to top

>> Your throttle body spacer is like others on the internet, why is yours better???

Each application is developed, designed and tested. If that particular product does not satisfy expected gains, we do not manufacture it. Taylor Cable Products has, on-site, their own Dyno-Jet chassis dyno. Some machine shops and manufacturers do not have this type of equipment. They will either copy something already made or make-up facts and figures to try to ensure a sale. >> Back to top

>> Will this blow up my vehicle???

Installing the Helix Power Tower is increasing the power level of the engine from 8-25 rear-wheel horsepower. If your engine expires due to this increase, there is really something else wrong. Most engine applications are designed with a tolerance of +10% and installing this product usually can fall in the 5-7% range. >> Back to top

>> I get a whistling noise as I accelerate, is this normal???

The first design would whistle, because of the sharp edge of the spiral. On the second design, a small hiss may be heard. Vehicles with an aftermarket air intake may amplify the hiss, as it acts as a megaphone and may make the noise louder than normal. >> Back to top

>> Can I drill and tap holes for my nitrous system???

Yes, but you may want to consult your system's manufacturer for specifics and technical issues you might come up against. >> Back to top

>> I do not feel any difference in my vehicle after I installed the Helix Power Tower. Why???

Each application has been tested for gains. There may be some situations though, that may cause this issue. The general tune of the vehicle, fuel pressure, restrictions, etc. While trouble shooting some issues, the following have been found: wrong spark plugs, clogged fuel filters, even incorrect ignition timing. Remember, these products were tested on stock, unmodified vehicles. Other modifications may interfere or hinder expected performance gains. >> Back to top

>> My CHECK ENGINE light is on after installing the Helix Power Tower. Why???

Review all connections that may have been removed or disconnected during the installation. Make sure they are properly reconnected and correctly installed. If that is not the case, verify the mounting gasket correct position. Do all of the holes line-up against the throttle body and/or the Helix Power Tower? Recheck any and all vacuum lines that may have become disconnected during installation. >> Back to top

>> My vehicle uses more fuel than before, is this something the Helix Power Tower does???

It is possible for this to occur. A couple of things to look for are: Is the driving style different than before, new product installed you would like to see how it does. If many items were installed during the Helix Power Tower installation, revert most back to stock and retest your mileage and then one-by-one reinstall your other upgrades. >> Back to top
