yes there is less to go wrong. lol well in all there are two less cyl involved. depends really on the year and the make and well the model. there are some that are better then others and yet there are some 6 cyl that are better then 4 cyl. what are you looking art getting that is either a 6cyl or a 4cyl

unless your getting a newer 4cyl mazda rx8 then the charge for spark plugs go outragious.

The only reason I asked this question is that many people say the six cylinder is a great engine, but, the reality is most people have the H4 and the majority of Subaru Outbacks are Four cylinder PZEV engines. There is no PZEV H6 offered. Does the PZEV engine do better than the non PZEV model in terms of maintenance? The only reason to get the H6 is the extra acceleration and power. Increased insurance and fuel costs come along with this feature.

they are typicaly about the same there is going to be some differences like kelly mentioned in the cost of tune up because there are more pars to be added like more spark plugs and more coils but in all reality I would rather go with the v6 then the 4 just for performance and power. don't get me wrong the 4 cyl have good performance. there is always posibility for some thing to happen here is some thing to do call a wrecking yar and find prices on a 4cyl engine and a 6cyl engine see what one is more expensive. I'm betting there right about the same price.

In most cases there's more power with the Six, except in the case of the Subaru WRX STI. It's a Four that has 305 horsepower and 290 foot pounds of torque.

A friend of mine just picked up a 2016 STI and said it was the best vehicle he's ever driven and is in love with it. Once the turbo spools up, the power is insane and pushes you into the seat and he hasn't even opened it up yet on the road. Boost was only at 11 vs tops at 20. I'd have to say he's not concerned about Maintenance costs.

Tom, thanks, yes, well if your friend just purchased a brand new 2016, it's under warranty and he probably has the funds to fix anything anyway. It's amazing how much power Subaru engineering got from their boxer H4 and only a 2.5L. The power of this engine rivals muscle cars from the 60s. I imagine it's not only the technology, but, the boxer engine design. In high school, people used to make fun of Fours, and would have never dreamed that an engine like this could be so powerful. I'm really surprised that some of the recent Subaru cars, particularly, the 2013 through 2015 Outbacks have had more complaints on www.carcomplaints.com. There's just not that many 3.6 H6 engines being sold on these cars. It's more like 80 percent of the Subaru engines today are the H4, just different versions for each particular model, with the WRX STI being the fastest. There aren't too many other engines on the market like it except for the Mitsubishi Lancer Evolution. http://www.torquenews.com/1084/mitsubishi-announces-473-hp- 2015-lancer-evolution-x-final-edition
