Has anyone ever done anything with the air filter. It seems like such a bad design. Stuck on the top of the engine getting red hot and no direct airflow.
There must be a better solution.
Any ideas?

I have thought about this myself TBH and I have seen P5B's with it removed and 2 x K&N filters stuck on in place. Not sure if they make much difference though due to again cold air flow over them but I would like to know the K&N part number if anyone has it to hand or has them fitted to theirs in place of the big box.
Regards,

I have them on mine, no idea on part number as I've had them unfitted for many years before my car was on the road. I've not driven them without, they can make the suck noise more audible and the engine is quite lively. The main thing is to keep them clean and oil them as specified.

Ive been using the K&N filters in all my cars for over 30 years now. They are the best in the world by far.
Just need to Rover v8/ P5B part number for them

Hi guys, Mines a 3 L so a bit more challenging, I had a V8 P6B, I had changed to an Edelbrock manifold and K&N filter. Was a big difference. Used a Mallory ignition system as well.

It would be interesting to know how you quantify "Was a big difference.".
What is your current 0-60mph time for example?

It was 12 years ago but there combination of the 10/1 compression ratio pistons, updated Cam, edelbrock manifold and Holly carb, Mallory ignition system did make a significant difference to fuel economy and it went like a rocket. It got wrecked in the end so in broke it and brought a P5 coupe with a 3l in. |

Here's another option if you want to go the pod filter route. This BMC B series engine (fitted with a alloy crossflow head) has 2 ram tubes fitted under foam pod filters. The ram tubes improve air flow into the carb throats. Several versions long and stubby versions are available with/without screens (UK).   |

But the distance between the car and inner wing is limited. I am leaning towards an remomte airbox. I'm really wish I could stop tinkering! Electronic dissy, reprofiled Cam, electric water pump, mechanical pump removed, twin electric fans. 20.65 to the gallon on a run. Done 550 m over the weekend. Ran like to Swiss clock. |

I'd like to make a suggestion. This isn't directed at you specifically, but many forum contributors.
I hope you don't mind.
When replying to a post, use the REPLY button rather than the QUOTE button, unless it's critical to readers to understand your post. This is particularly important when the post you're replying to is long or contains photos.
It avoids those long posts or photos frequently being repeated over and over again through the thread, significantly increasing its length and often reducing its readability.
If you're replying to the last post in a thread, then there's usually no need to quote at all. Your reference will be obvious.
It's also not widely understood that if you do use the QUOTE function, you can edit the quoted section and remove photos or other parts of it that you're not commenting on. It's quite easy.
Another problem often encountered is when someone quotes a post and then types their comments inside the quote itself, often making it quite confusing to read.
And while I'm on my soapbox, I'd like to point out to newer members that if you accidentally make an error or post the same thing twice, you, as the post's author, can easily go back into it and edit it, or delete it altogether.

Just need to Rover v8/ P5B part number for them Brendan, I know this isn't in the UK but it should be a good start in searching for the part you need. www.carid.com/knn/round-tapered-red-air-filter-5-f-x-6-5-b-x-4-25-t-x-8-h-mpn-ru-2805xd.htmlJust measure the outside diameter across the carb inlet and then search the equivalent K&N, it should be quite straightforward to find. If it helps I'm pretty sure the diameter is the same for P5B, P6B and carb V8 RangeRovers of the 70s and 80s. Theres a good chance the V8 SD1s are as well. So if you find one for a Rover V8 of the era it will most likely be the right one. Roy (quoted so he gets a notification of my reply) |

Cheers Roy. I think your 100% spot on too. They are on a list of things to look at during the coming months. At the moment I am doing Heater system research and self investigation with a view to getting it all working as its supposed to do along the entire systems run front to back. LOL.

I found an old reference in the " club members only " section referring to the K&N air filters for the P5B and other associated Rover V8 engined models.
Its K&N - E - 9098
Gonna take a looksie at these and then maybe buy a pair.

Try and get a visual to make sure they aren't meant to fit in the original air filter box? Good find though.

Post by Sam Bee on Jan 16, 2019 18:50:15 GMT
Brendan, the E- 9098 is meant to fit within the air box and looks to be the wrong shape. The conical ones that fit individual carbs is RC-2600 according to K&N.
Go to the K&N website for detailed info.

A bit of research turned up SC Parts who do a filter that fits the standard box. They specifically state on there website for Rover V8 in Discovery and Rover P5B; not tried them but they look correct. £6.99 each.

Cheers guys and yes ive seen both styles too with OEM airbox and without. Abit more investigating first I think before I commit.
On removal and inspection of my air filter box today I noticed a oval shaped hole in the main body top covered by masking tape. Anyone know what the hole is for and why it could be taped over???
I also have 2 x quite dirty Cooper filters fitted at the moment with the orange rubber bodies on them. I have tried for the last hour on the K&N site to see if I can find a match but sadly I cannot. Has anyone been successful here and found an identical K&N match???
The markings on my 2 Copper air filters are not very clear either even under a magnifying glass. Ive also seen other types too which just look like white paper elements with no rubber body to them. JRW sell these along with other Rover part sellers too in addition to the rubber bodied Cooper versions which TBH I prefer to use for a better seal when fitted. I imagine when new they were round in shape and change to an oval once fitted
