Best heavy duty battery

[Andrew120960]

Hi, 

 

I'm new to the forum, i have a BMW x5 2005 e53 4.8is, I've converted it to run on LPG, I'm looking for a decent spark plug and a stop start battery, heavy duty, any suggestions please, thanks, Andrew.

Morning Andrew

Welcome to the Forum 

First Battery check wwww.realoem.com put the last 7 digits of your Vin into the search box it will call up your model. Then look at the relevant section for the information you need.. When changing battery make sure it is correct for the car and is registered to make sure it is charging correctly. An over rated battery won't last any longer and may not charge correctly. And lifting the LPG tank to change battery is a job you don't want to do very often (been there done that 🤣)

Spark plugs in my 4.6is are BERU Z116   14-FR-6 LDU been in the car for almost 5 years now (about 30k) never missed a beat but there are offerings from Bosch NGK Champion and others

Have a great Christmas enjoy your Beemer
