Bosch isn't in the same league as Denso and NGK in terms of iridium plugs IMO. Best to stick with NGK and Denso, no reason to go with Bosch or anything else since they aren't any cheaper.OWS has spark plugs? Aisayman. There are three major manufacturers that make good plugs, Denso, NGK and Bosch. All others are niche brands with niche 'features' like silver tip or pure copper and all that. You want standard stick with standard brands la. I usually buy from spare parts shops and usually go in with what I want. Don't compromise your decision unless it's the equivalent alternative of a well known brand.
Oh btw, whats the heat range on the plug you bought vs the original?
The latest stupid brand is AVS. Center electrode breaks off in the engine. Avoid.
