I'm spitting feathers, but maybe you'll benefit were I missed out... had been half watching out for a while for a good price on genuine Bosch injectors for the MK1, in my case it was specifically 0 437 502 023 which for some reason are always more expensive than say those for the Cabby for example. A current multi-buy 7% saving from 'Carpartsinmotion' via eBay brought them down to £30 each inc. post from an already competitive price which is as low as I've seen them. Typical - 3 days after I got mine eBay are running a 20% off voucher (ends 23:59 on the 31st Jan '23) that runs along side the existing 7% offer - means you'll get another £24 odd quid off on top. 4 x new Bosch injectors for less than £25 each delivered... some second hand ones are asking more!
