We have 2 Astra Gs, a '99 1.6 16v LS hatch and a '00 1.8 CDX saloon.
The 1.6 has 2 plastic strips, about 5cm x 50cm, attached vertically to the underside just in front of the fuel tank. The 1.8 has no such strips. I've seen one or two Astras with them but mostly without.
What are they for?
Would the 1.6 be better without them?
Would the 1.8 be better with them?
I'm just baffled, please help!
