BOSCH 4 HOLE INJECTORS??

[Southernboy]

Has anyone seen this option for BMW Z3's...seller claims this is an upgrade from the OEM 2 hole injectors ???

Bearing in mind that the newest Z3s are now 10-years old, we don't seem to see many threads about either fitting new injectors or getting the old ones professionally cleaned.

These 4 hole injectors are purported to improve fuel economy, provide smoother engine running and improved fuel distribution / combustion...I thought it might be a sound upgrade if anyone with "rough" engine performance was to consider an injector replacement. They're selling at £116.50 for a full set including all new seals etc..eBay - UK

That's not a bad price for brand new - do four cylinder models get a 33% discount? . I've had the attached on my watch list for a while as they are not that far from me.

Looks like a good idea too...I wonder if the injectors ever become brittle with the heat generated at the cylinder head, and if they develop cracks etc...Surely they must eventually wear somewhat??
