Signs of a faulty part

If you notice any of the following, the part likely needs replacement:

  • Loss of power or torque in certain rev ranges
  • Check Engine light with an intake runner control fault code
  • Rattling noise from the intake manifold area

Installation information

Bolts to the intake manifold with a seal, and connects to a vacuum line or electrical actuator — check the actuator moves freely before finishing installation.

Frequently asked questions

It physically changes the length of the intake runners — shorter for high-RPM power, longer for low-RPM torque — giving the engine better response across the whole rev range.

  • I ordered a Heater Blower Motor Resistor for a Toyota Avensis. Delivery took eight days from Latvia to Ireland. I installed it, and everything works perfectly. I wish this company success.

  • No complaints about Evro Trans itself, everything's fine. But the delivery..... It felt like the order was being carried by turtles. 4 days from Riga to Daugavpils. Judging by the tracking, the parcel just sat somewhere behind a shed for 3 days, then they found it and delivered it the next day. I think that's why I won't be ordering there again.

  • Bought a front fender for my car. I liked it! After payment they sent more than 20 photos of the problem areas, and it was packed very securely - took a while to unwrap.
