Essential Fuel and Emissions Systems for 2021 Acura TLXes
aFe POWER – Sprint Booster (Part No.77-16604)
from
$339.99
Automobiles in the 21st century have replaced the more conventional throttle cable technology for an ECM (Electronic Control Module) that translates pedal travel into electronic signals in order to provide power to the wheels. The ETC system (Electronic Throttle Control), also known as drive-by-wire, has the unfortunate downside of delayed throttle response and subdued acceleration, creating problems in certain circumstances such as up-hill starts, quick gear changes, overtaking, etc. The Sprint Booster aims to overcome this throttle response delay for ETC-equipped vehicles, providing crisp on-tap acceleration at the driver’s disposal.

Carquest Premium – Fuel Tank Pressure Sensor (Part No.ECA1299)
from
$76.99
Pressure sensors are used within several operating systems on the vehicle. Subjects in this category measure the pressure of both liquid and air to include air in a positive pressure and negative pressure range. Pressure sensors report out as the result of an electrical device called a strain gauge which produces an analog or digital signal output dependent on the needs of the circuit. Pressures may be very low such as barometric pressure, or extremely high such as in a high-pressure fuel injection system.
