The Ultimate Porsche Boxster Tuning Guide

The Porsche Boxster is a cracking little motor and is popular with thousands of people in the United Kingdom and beyond! Sometimes known as the German carmaker’s baby car, it is also one of the most affordable Porsche models you can buy – brand new ones are only £38,237! But regardless of whether you own a brand new one or you have purchased a used one, many Boxster owners want to improve the performance of their cars.

Why you should tune your Porsche Boxster

Car manufacturers typically limit the capabilities of what their models can do for two main reasons:

  1. because engines need to comply with strict European emissions standards;
  2. because development teams have to stick to a set budget and time limit for producing new models and engines.

Any car, whether it be a small and economical 1.0-litre 12v or a thirsty 5.7-litre V8, can be tuned to provide better performance and in many instances better fuel economy. So if you have a Porsche Boxster and you want to unleash some extra horses from your fine piece of German engineering, here are some awesome ways for you to do so.

Before we begin: a note on Boxster engines

Porsche engines are usually pretty solid and reliable blocks. However it is worth noting that some of the engines in 2000 and older models are prone to cylinder head liner cracks. But thankfully, this issue has been addressed by Porsche in post-2000 models.

The best engines to tune are the 3.2-litre ones, but even if you have the 2.5-litre model it is still perfectly possible to tune those, as well.


This is the first area that you should look at when improving the performance of your Porsche Boxster. There are a couple of options available to you here, such as getting an uprated panel filter for your air box.

This replaces the standard paper filter, and because it is washable, it means that you don’t have to keep forking out for new ones every time your pride and joy is serviced.

Induction kits also offer improved airflow into the engine, as they offer a cylindrical cone filter to replace your OE air box.


All exhaust systems on modern cars are fairly restrictive, as this is required to help the car pass European emission standards.

Many Porsche Boxster owners opt for a more free-flowing exhaust system, such as one made from stainless steel, and some even go as far as replacing the OE exhaust manifolds for high flow stainless steel ones.


Something often overlooked by many car owners is the necessity to have their car fully serviced. Even the most frugal of car owners will notice improve response from their car’s engine simply because it has fresh oil and a new oil filter, and uprated spark plugs and leads will also ensure a cleaner spark – leading to better performance.


One thing that will help you get the most from the previous suggestions is by having your engine’s ECU remapped or “chipped”.

A specialist engine tuning company will be able to provide a custom map for your car which is designed to take advantage of your modifications, and they will be able to put your car on a dynamometer (commonly known as a “dyno” or “rolling road”) so that they can measure your Boxster’s power and torque values before and after your remap.

Alternatively, for standard Boxsters with no modifications, you can either get a set map which you can upload or remove yourself (such as the Superchips Bluefin).
