Waste of money tbh, you will never notice that supposed upto 5 bhp.
If I had a race engine, then yeah I would possibly get it, actually no, I wouldn't even have the standard oil system because its one of the weakest points when going high power... and for a normal road going engines - no point what so ever unless your oil pressure was shitty, but then why bodge it with one of them.. I'd personally want to fix it good and proper using standard parts and know it's how it should be.
IMO.. waste of £38
