i have seen Kedai "Abang" got them. 2 types available. The good ones has cloth inside while the outside is plastic sheet. Comes in various sizes for diff cars. If not mistaken, it about RM150.00. That was almost a year ago.
The cheaper plastic ones better not buy. The seams are bad and will koyak very fast due to thin material used.
I had been driving all day 1000km highway driving.. stopped for a break and when i started driving again i noticed that the standard turbo in my evo 8 wasnt spooling up. the boost gauge was reading vacuum...
