Is it dangerous to keep driving with a cracked pipe here?

Not critical immediately, but the resulting air leak can affect engine performance and trigger a check engine light — repair when convenient.

Can the pipe be repaired instead of replaced?

A hose clamp or tape might hold a small crack temporarily, but replacement is the reliable fix.

What is the pipe made of?

Reinforced rubber or moulded plastic.

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.
