Any recommendations as to the best one for the C4 please?

I did just that. I also bought oil and air filters Citroen recommend 5 w 30 fully synthetic oil. Could I use semi synthetic? It's just that I have loads of it lol Thanks

It's the 1.6 but not the vti engine I don't think Thanks

Ngk, Denso or Bosch Eurocarparts do all 3. The Demso ones go from around 3.49 to13.99 each??? Thanks

For better or for worse I have agreed to buy a C4 automatic. It is a 2007 with a low 32500 on the clock. It's costing me 2k, which seemed reasonable. Now one small issue we had test driving it is the gearbox kicked up a fault. We were going up a hill at the time. I trust the guy we are buying from and know he'll get that sorted. He's a garage owner and he's giving me 3 months warranty on it. It went into 3. This was solved by pulling in and restarting it. It didnt happen again on the test drive. Any advice? We haven't bought it yet. Thanks
