Review of BERU UTP spark plugs for G3

Yokohama Geolanders, Sony head unit, NAUTILUS Air Horn, DRL conversion, Rear cargo space, Elvis Bobblehead, transfer Guard, Indian hanging Elephant, Koni Heavy track dampers, Custom SS exhaust, Voodoo Doll, Adventure Rack with LED ight bar, vintage ERIBA caravan usually attached (yes it's slow)
Review of BERU UTP spark plugs for G3 was created by Scimike
Spark plugs are a mine field of costs, ranging from £3.50 to £24.00 each.
Avoiding all the magic performance claims the big one for the more expensive plug is service interval. The cheaper plugs have a manufacturers claimed life of about 10K, or fit every year. At the other end NGK Iridium claiming over 60K.
You need to do your own maths as to which is cost effective for you, but how do they actually last in real life.
The cheap end do exactly what they say, change them every year.
But I've tested a set of medium priced BERU plugs, and here is the result:
Make - BERU UTP11P sold by many motor factors
Cost - £8 to £16 depending upon offers
Construction - Look like Iridium but difficult to find information
Manufacturers Life - Again not stated, but at £16 they need to achieve 40k to beat cheap plugs
Do they work in a Jimny - YES
Condition after 20K - Starting to exceed adjustment limit of 1.1mm / need replacing
Would you recommend ? - No, service lift too short for cost of plug
Some pictures
Four plugs as removed from 2009 M13A VVT after 20K miles.
You can see electrode erosion on the left plug, two within limit, two just out of limit
I am in the process of running the same test on NGK Iridium plugs, they claim 60K plus, so hopefully they will do better. One issue with long life plugs is the Suzuki service interval of 4 years for this type of plug, expensive if they can't exceed this.
Hope some find this interesting even if it's to only avoid BERU UTP plugs as a long life alternative.
