Something about Gladiators is just staunch đź’Ş

We have just done a 4.88 re-gear on this one to accommodate larger tyres and shift the torque into a more usable rev range.

Ratios are available in 4.56, 4.88 and 5.13 for these vehicles, accomodating tyres up to 40”

We recently did a post on fuel filters

Today we are talking about air filters.

If you don’t like your diesel or petrol engine, please don’t change your air filters. You will be able to choose a new replacement engine really soon.

For those of us who love our cars, please change your air filters. Otherwise you get to buy new turbos and other expensive things.

In this instance we can see where dust and foreign objects have been abrading the compressor wheel. This compromises performance and ultimately destroys both the turbo and engine. You can see the difference between the old turbo and the new one by the profile of the fins.

So please inspect and change your air filters regularly, and for anyone with a Toyota especially, call us and upgrade your airbox.
