How can I tone up my engine for jeep wrangler sport 2012 ?
If you mean tune up....about all that is required is spark plugs, belt(s), all filters and fluid changes including transmission, engine oil, differential, transfer case, coolant and brake fluid. Spark plugs should be good for 100,000 miles. Refer to the owners manual for the suggested maint. items schedule. If you don't have an owner's manual get one at www.helminc.com.
