So, after work, took the opportunity to do something that's been on the back burner for ages: I think it's the first engine performance mod! A RacingLine R600 air intake! Alongside other bits such as: Turbo inlet pipe, and additional bits like a replacement pipe to go underneath the new air box bit. These bits were bought absolutely ages ago, circa March 2024, and have been lying around since. The R600 main bits were £502.93. The turbo inlet pipe was £74.99 and the coolant pipe was £42.94. So the first step is to start removing the original air filter box and inlet. Two screws, and the front should wiggle away: Then used a flat head screwdriver to loosen and pop out the vacuum line from the air box: Then my Knipex pliers to get the clamp off of the air intake pipe: Once the pipe is loosed from the air intake box, the air filter box itself can be removed, as its some rubber grommets over plastic bits: Popped out with effort, and unfortunately: Looks like I got too hamfisted and ripped out one of the plastic bits with the rubber! Guess a new battery tray required... So those bits out so far: Next is to replace the coolant hose with the replacement designed to go under the R600 box. Lots of Youtube videos show coolant going everywhere, and to be honest, I did the same. Got towels and whatnot underneath and just removed and replaced as quick as possible: Got messy so no pics for the other side. Wiped excess and some parts cleaner before the next bit. So dry fitted the bottom part of the R600 box: Just some wiggling really, but noticed the instructions mention attaching rubber grommets to the box before installing them: Sadly, the packaging didn't have any! Plus with the broken plastic bit in the battery tray, kinda stuck for now. I expect rattling until this is sorted I guess. So carrying on, time to remove the air intake from the filter to the turbo inlet pipe: Standard hose clamp, so a 7mm to loosen, and then wiggling to free that pipe: So next is the turbo inlet pipe. There's a hose that needs to be removed, via squeezing and popping it off. Then also a T30 torx bit keeping the pipe in place. Once removed (carefully lest that torx bolt drops into the abyss!), initial attempts to pull the pipe off wasn't fruitful. Turns out it needs some rotating before it pops out: The new one is the reverse. I put a light smear of engine oil on the o-rings that the new RacingLine pipe had, then pushed in and rotated into place: Then carefully put that torx bolt back into place. I tightened it to 12Nm as its an M6 bolt, not sure what the actual figure needed is. On the home straight now. The R600 kit came with a new pipe, so slotted that in alongside the filter itself: Just some wiggling but it eventually all aligns up. Orientation of the pipes and stuff was probably made simple by just looking for the RacingLine logo and making sure that points upwards! Not forgetting the vacuum line: That's pretty much it, on with the top cover: Tighten up all the hoses and bits and that's that: Noticed also that the R600 box didn't have any screws, so decided for now to just take a few from the OEM air filter box and attached them to the R600 box. Will need to source rubber grommets for the R600 box and screws if available. The spoils: So will need to find somewhere for these OEM bits to go, but that's that! Haven't really driven it in anger yet, I'd imagine there probably won't be any major difference really. Am hoping this becomes useful once a remap is involved! Bit annoying that some of the bits were missing, but some Googling has shown replacements are available, so I'll order those, and probably a battery tray as well, so technically some of this will need disassembling once those have arrived.
