airflow meter

[ger man]

Hello,
Anyone have experience with the airflow meter manufactured for TVR Parts by Lucas?
Mine is broken and i need another.

Regards Dennis

Its a bog standard Range Rover 3.9 part, lots in scrap yards. You can use either a Lucas 5AM or the older 3AM is plug compatible- but you may need to strip the end castings off your old one to make the pipework fit. I think the supply of new Lucas ones is becoming poor, but last time I saw a genuine one it as around £200 new. There are lots of Chinese patten ones on Ebay for around £50, and most my experience of these is bad (poor response, calibration and heat resistance) but I came across someone who had bought one that worked OK, so take you chances on that one.

Agree I had a Lucas one fitted by a mechanic and it had a Bosch part number on it and Lucas sticker, Griff would run right and a well known Tvr garage told me it was a cheap Chinese copy so beware

My original was dodgy and Joolz at http://www.kitsandclassics.co.uk/ fitted a used genuine Lucas - he said the chinese new ones just aren't as reliable.
I'm guessing it's probably the underbonnet temps on TVRs that kills them - you can get a little silver AFM overcoat to keep them cool - they're in the classifieds.
It'd be interesting to see a "meter manufactured for TVR Parts by Lucas" - I didn't think Lucas still made them
