My 06 1500 Hemi has 160700 miles. I want to put on a few engine upgrades. What to do and why? It's all stock except for tires and wheels. I bought it at 124000 miles 2.5 years ago and have only done oil changes to the engine. Haven't changed plugs yet.

 

We are a lot alike. I have an 06 with about 164,000. So far I've done plugs, wires and air intake system cleaner (3 stage) by BG. Recently my alternator and thermostat when out so i had to do that as well. On my 04, i had an intake and superchip flash, but that seemed to rob my gas mileage . I'm thinking my next upgrade for my engine will be an efan.

So if youre looking to get better mileage, get an efan. If you want more power, do an intake and chip. I love the BG engine cleaner, so i wouldnt overlook that due to the mileage your truck has.

 

I'm freakin poor and I think the Hemi has plenty of power @ stock, so those upgrades seem great to me! I'm driving this thing until the block falls apart.

What have you had to do to the front end or the rear driveline?

 

My 04 Hemi has 94k (bought with 76k). I haven't done much maintenance to it yet aside oil changes (plugs soon). Put on the K&N intake as its one of the few Cali legal ones. Loved the difference. The Hemi really responded to it. I also ditched the stock muffler and resonator. Had a single chamber Cherry Bomb installed. I can tell she breathes better than before. MPG's havent changed too much. When I baby it i'll make a full 35 gallon tank last a month (I drive 5 miles to work round trip). When I get on the throttle the Hemi roars and will even spin the 33" mud tires real easy but of course the low MPG helps me choose not to.

 

All depends on what your budget is lol

 

I would start with some new plugs.I don't know how many miles you have put on it,but after 2 1/2 years you are likely getting close to the 30,000 mile suggested plug change interval.The copper ones are pretty cheap.

A DIY CAI is another cheapish option.The general opinion is that they are about as effective as the ones guys pay hundreds of dollars for.It won't give you huge gains by itself,but it is another addition towards gains.

A "Y" pipe and a freeflowing muffler can be welded into your existing exhaust(assuming its solid) for much less than a catback system, and will help your air flow a bit better.
