Sylinderbyttet står i pristilbudet.

Because Norwegian very often makes compound nouns where English would use two or more separate words.

• sylinder = cylinder
• bytte = change / replacement

So sylinderbytte means cylinder replacement.

Then the ending -t makes it definite:

• et sylinderbytte = a cylinder replacement
• sylinderbyttet = the cylinder replacement

So sylinderbyttet is not unusual at all in Norwegian; it is the normal way to write this kind of noun.

In Norwegian, the definite article is often attached to the noun as an ending instead of being a separate word.

Here:

• et bytte = a replacement
• byttet = the replacement

Since sylinderbytte is a neuter noun, the definite singular ending is -t:

• et sylinderbytte
• sylinderbyttet

So sylinderbyttet already includes the meaning of the cylinder replacement.

Here it is a noun, not a verb.

That can confuse learners because byttet can also be the past participle of å bytte (to change / swap).

But in this sentence, it is clearly a noun because:

• it comes in the subject position
• it matches the compound noun sylinderbyttet
• the sentence structure is [subject] + [verb] + [prepositional phrase]

So:

• Sylinderbyttet = the cylinder replacement
• står = stands / is stated / is listed
• i pristilbudet = in the quote / estimate

Yes, står literally means stands, but in Norwegian it is also commonly used in a more extended sense.

In contexts involving writing, documents, and information, stå can mean:

• be written
• be stated
• be listed
• appear

So Sylinderbyttet står i pristilbudet means something like:

• The cylinder replacement is stated in the quote
• The cylinder replacement is listed in the estimate
• The cylinder replacement is included in the quote
  depending on context

This is a very natural use of stå in Norwegian.

It literally means in the price offer, but in natural English that is usually:

• in the quote
• in the estimate
• in the quotation

Breakdown:

• pris = price
• tilbud = offer
• pristilbud = price quote / estimate
• pristilbudet = the price quote / the estimate

So i pristilbudet means that the item is mentioned or included in that quote/document.

This is mostly a matter of Norwegian usage.

With documents or written content, Norwegian often uses i where English might use in or sometimes even where English might think of on.

So stå i et pristilbud means:

• be written in a quote
• be listed in an estimate

You should learn this as a normal collocation:

• Det står i kontrakten. = It says so in the contract.
• Det står i e-posten. = It says so in the email.
• Det står i pristilbudet. = It is stated in the quote.

The sentence has normal Norwegian main-clause word order:

• Sylinderbyttet = subject
• står = finite verb
• i pristilbudet = prepositional phrase

So the pattern is:

Subject + Verb + Other information

This is the standard word order in a simple statement.

You could, but it usually sounds less precise or less idiomatic in this context.

• står i pristilbudet suggests that it is written/listed/stated in the quote
• er i pristilbudet more literally means is in the quote

So while er i is understandable, står i is the more natural choice when talking about information appearing in a document.

Both sylinderbytte and pristilbud are neuter nouns.

You can see that from the indefinite article et:

• et sylinderbytte
• et pristilbud

For neuter nouns in the definite singular, Norwegian usually adds -et or -t:

• et pristilbud → pristilbudet
• et sylinderbytte → sylinderbyttet

So the endings help you identify both the definiteness and, often, the gender.

Yes, pristilbud is a normal word, especially in business, repair, construction, and service contexts.

• tilbud can mean offer, and sometimes special deal/discount
• pristilbud is more specifically a price quote or estimate

So if someone is talking about work to be done and cost, pristilbud is more exact than just tilbud.

An indefinite version would be:

Et sylinderbytte står i et pristilbud.

But this is less likely in real life unless you are speaking very generally.

More often, in real contexts, you would use the definite forms because you mean a specific replacement and a specific quote:

• Sylinderbyttet står i pristilbudet.

That is why the original sentence sounds natural.
