Holley offers a complete line of carburetors, fuel injection systems, throttle bodies, fuel pumps and much more.
The use of nitrous oxide (N2O) as a performance enhancement has been traced back to World War II, where it was employed to give Allied aircraft "emergency" boosts in both airspeed and altitude capabilities. However, with the advent of jet propulsion at the end of WWII, the government's interest in piston-powered aircraft waned, and for the most part, nitrous R&D was shelved.
In 1978 Mike and Dale formed Nitrous Oxide Systems, Inc., and the rest is history. They didn't invent nitrous oxide -they simply perfected its use and elevated it to a position of prominence in the automotive performance community.
Today, with over twenty years experience building nitrous systems for racing and street applications, NOS remains THE dominant force in the industry. A great deal of the company's success can be attributed to its ongoing pursuit of perfection and extensive R&D efforts. Another key factor is the relationships that NOS has forged with leading racers and professional engine builders. Their input has served to keep the company on the leading edge of technology.
Each Performance Distributor is custom-tuned on a distributor machine with a super smooth advance curve. A custom advance curve insures maximum performance and mileage. Buying an "uncurved" distributor would be like buying an unground camshaft! No compromise curves...no guesswork for you. Just pure power from the world's leader in high performance advance curves.
Chips/Modules & Programmers
Painless Performance now offers Diesel Performance Upgrades. They offer everything from performance modules to waste gate controllers. Check it out today.
Superchips offers a complete line of hand-held tuners to cover most domestic cars and trucks. While we are famous for the incredible power gains (12% increase in HP on gas vehicles, up to 150HP increase on diesels), our engineers and calibrators design the products for drivability. No more downshifting on big hills, we tune throughout the powerband for consistent performance from 500 to 8,000 RPM. In addition, our customers rave about the fuel efficiency gains, even while picking up, on average, 50-60 extra horsepower.
We call this usable power - all the way across
the power band at the speeds and in the gears where you need it.
Our system also produces a very flat torque curve. This means, once our maximum
torque is reached, torque falls off very slowly as RPM's increase toward maximum
horsepower. This gives your engine excellent pulling characteristics by keeping
torque output high all the way up the power band until maximum horsepower and
RPM is reached. (JUST IMAGINE!)
One of the most frequent complaints we hear about stock engines is slow throttle
response. Our system significantly increases throttle response right off the
bottom and all the way across the entire RPM range. You'll know it when you push
on the pedal. Improved throttle response combined with the extra power, results
in a much more enjoyable driving experience. You will be able to merge, pass,
and move away from undesirable traffic situations in ways you never thought
possible with a larger vehicle. You may be able to accelerate in up to half the
time. Your speeds under load will increase 20-35 MPH on grades of 5 to 8%.
Grades of 5% or less will no longer slow you down at all.
JET Performance Products is a leader in tuning technology. Constant changes in computer technology of today's cars and trucks demand that JET's engineering staff be the best. We are dedicated to providing the customer with the best tuning possible. Jet offers power pulleys, chips, modules and can reprogram your import factory ECM.

Cold Air Intake Kits
AIRAID Intake Systems are specifically designed to take full advantage of today's vehicle technology. Our performance success story is really quite simple - we use the latest dyno-proven techniques and innovative designs to improve upon intake system efficiency. Therefore, the greater the efficiency level, the greater the horsepower. AIRAID Filters provide a dramatic improvement over factory air intake systems. Increased airflow of up to 20% and gains of over 15HP are common. AIRAID installs in 30 minutes with common hand tools, with no cutting, drilling or fabrication
| Advanced Flow Engineering, Inc. (aFe) produces high flow, high performance air filters for the automotive industry. Founded in April, 1999, aFe was created to address an obvious need in the automotive aftermarket industry: a lack of choice for a high performance aftermarket air filter. |
| We are a team of engineers, machinists, production and sales people who believe in the product we design. We each have years of experience in our respective positions and together work to ensure that we have the best product on the market. Our purpose was not just to be another vendor that offers air filters, we chose to pay attention to those finer details that set an aFe filter apart from the competition. |
| We currently offer aftermarket air filters for passenger cars, light trucks and SUV's. We also have many applications for round racing and universal clamp-on filters. |
K&N Engineering, Inc., "manufacturer of the world's best air filters", has been the innovative leader in air filter technology since 1963, serving the needs of the automotive, motorcycle, marine , industrial and military markets. Located in Riverside California, K&N also has another manufacturing facility in the United Kingdom.
Performance Clutches
CENTERFORCE® clutch systems are designed with the
diverse needs of the customer, or end user in mind. Because of these diverse
needs, Centerforce® offers a multilevel line to meet the requirements of a wide
range of vehicles and their intended uses. To obtain the proper system, it is
extremely important to completely qualify and verify the vehicle, not only by
its make and model year, but also "define" its intended use. A stock
vehicle used for commuting to and from the work place has an entirely different
requirement than a "high performance" vehicle driven at the extreme of
its capabilities, and sometimes beyond!

Cat Back Exhaust Systems
Every Gibson Cat-Back System is performance tuned and engine matched to unleash your vehicle’s full potential. All exhaust systems are emission legal in all 50 states and do not affect vehicle warranty. They are well-suited for lowered or raised pickups and tow vehicles because the performance gains are engineered to come in at low and mid-range RPM-highway speeds. Gibson offers single, dual, split rear, super truck and dual extreme. They also offer performance headers and exhaust systems for diesels.
Headers
JBA Headers is an industry leading manufacturer of 50 state smog legal headers and exhaust products. The innovator of the first smog legal aftermarket "shorty" header, JBA has established the standard for performance exhaust products with patented technology like the JBA Firecone® collector and standard features like heavy-wall tubing, thick 3/8" laser-cut flanges, and easy no-leak installations.
Throttle Body Spacers
The POWERAID® TBS concept was developed to
enhance mid-range power, torque and fuel efficiency. The unique dyno-proven
"Helix Bore" of the POWERAID® TBS causes a spinning action of the
incoming air-charge as it passes through the throttle body. This extremely
beneficial air-charge carries all the way into the combustion chamber, producing
a super-atomized mixture, which produces tremendous gains in mid-range power and
overall efficiency. This is the key element to the horsepower success behind
each POWERAID® TBS.
