There are a lot of times that a mechanic has to wonder what the engineers that designed the car were thinking. Bolts barely accessible with any wrench, parts in odd places, etc.
One of my least favorite examples is the oil filter on some Subarus. To reach it you have to reach between hot exhaust pipes on every side. Easy to burn your hand and arm if you aren’t careful, but it’s pretty impossible not to touch the pipes, especially when trying to tighten it all the way.
Oil filter is a good source of removing dust from your engine and increase the life of your engine, A car engine cost more than an oil filter, So, choose filter wisely.
