I have read loads about DV valves and how the standard Bosch ones are a bit rubbish etc. Can someone please help? I have a 1997 Passat 1.8T
20V and am about to have it chipped by Upsolute. I thought I'd upgrade the DV but it's not the same design as the 710N Bosch ones. The 710N type won't fit. The DV on my engine is to the front left when looking at the car from the front. Would the APR R1 fit or the Forge 007 "A Line". Anyone know which DV will fit my '97 engine? I'm also not sure which K&N air filter I need. Is it the 33-2125 (for the 3B chassis number like mine) or the 33-2675?Last question. I am also going for a different spark plug- a cooler one. The NGK BKR7E seems cheap enough (gap 0.028"). This okay?
Thanks
