HT Leads

Post Mon Dec 10, 2012 12:15 am

Hi, I want to replace my HT leads aka ignition cables/leads on my 89 318i. Bosch offers 2 variants, B325 and B328. How can I know for sure which one to order? They are both listed for the same engine..

The two sets of leads are for the same engine in two different cars - E30 and E36, but as willnz says, they are very unlikely to need replacing unless physically damaged, and even then good second hand OE is the way to go.

Ok thanks, I want to change them just for the sake of it, it is a common tune up in my native Canada... Been away for a while now and will finally get to change my injectors, seemed like a good idea. I don't know how to measure resistance : )

Common enough tune up in the UK as well - if you own something like a Land rover or a Ford (who use burnt string for leads!)
Not all vehicles were created equal.
